I think I found out why your mod causes null reference errors now.

extendsMaintenanceCluster and maintenanceClusterRadius do not appear to exist in the base game files. They are referenced in the modding API, but they don't actually exist.

Yep, this absolutely breaks the game. Nullreferences in console, and I can't build regular maintenance buildings anymore as it all freezes while one is selected. I must destroy all Tier 3 to get back proper control of all this. :/

Actually, it entirely breaks the maintenance grid. It can no longer show amount of drones or anything.

This appears to cause the game to lock up when trying to place Tier 3. It seems that somehow it breaks the game's placement system as it shows both Maintenance range and power range. Causes very bad glitchy placement sometimes freezing it completely till you select neither electricity or maintenance placement options such as traffic.

haven't had any problems playing with this mod in the current version

Any news?

Any chance on this getting an update? Not compatible with the current version.

is it possible to merge this mods stuff into one that implement its content into hubs ?
i hate it to build batteries just to expand my power grid

Sorry, I haven't followed updates for a long time and this mod probably doesn't work with the latest game updates. I'll try to fix the problems soon.

The building still ignore terrain. What ever was causing my issue 2 posts ago is gone. Something else was messing with the ultimate hubs.

Also, The buildings from this mod ignore terrain. I'm not sure if that was intentional.

When I select the Universal Hub to start putting them down, the maintenance lens activates and I can't put any Hubs down. When I turn the lens off the hubs are placeable.

YAML error. A shame because I would LOVE to get better range on maintenance buildings.

Sooo.. has the upgrading bug ever been fixed?

think the problem is you have one building trying to do to many things at one time and its causing it to bug out

Correct. Both bugs - bugged maintenance view and bugged maintdrone production - are caused by tier 3 that were upgraded from tier 2. That means that building only tier 2s *or* only tier 3s (from ground up) will not reproduce them. Try this:
0. make sure there are no tier 2s nor 3s on the map
1. build a tier 2 - everything should work
2. build a tier 3 - everything should still work
3. upgrade tier 2 to tier 3 - now the maintenance view should bug out *and* you should have two tier 3s, only *one* of which should be producing drones as intended - the upgraded one should be bugged
4. now, scrap the bugged tier 3 and the maintenance view should be fixed too.
I'm sorry I can't help by a video clip or something, but alas, I have no experience with screencapture :|

You mean building tier 3 doesn't produce that bug?

Um, why remove the repair function from tier 3 if it's not the problem? To reiterate: tier 2s work fine, NEW tier 3s - including maintenance drone production - work fine. UPGRADING tier 2 to tier 3 is what's broken - if anything I'd suggest removing that function.

I think at the moment the only way to fix this is to remove the repair function from tier 3 and just add more stats.

I was curious, so I did some experimenting. Long story short: DO NOT upgrade tier 2 to tier 3 and all will be fine. Both work fine if built from ground up; you can build - and use - both tier 2 and tier 3 but scrap tier 2 and rebuild as tier 3 instead of upgrading - it bugs the building out and is the reason of all the issues (definitely not memory issue - my bad). Also, scrapping all bugged (upgraded) tier 3s will remove the problems.

I just encountered identical problems but luckily also stumbled upon a workaround. First, Universal Hubs are fine if built from ground up - it's upgrading from tier 2 to 3 that bugs up the maintenance drone production. Secondly, about the maintenance view freezing: it seems to work fine for some time after launching the game, and also after it starts acting up I can "unfreeze" it by zooming the camera closer to surface (it will freeze back if zoomed back out though); it might be memory-related but I'm just guessing at this point.

I'll try to figure out what can be done about it. Unfortunately, there is not much information about how the resource request functionality actually works.

Sorry for so many messages in a row! Found one more issue with the tier 3. It seems that they do not properly request the goods required to construct repair bots. I've tried turning off EVERY other possible destination for polymer and electronics, but all the tier 3 Power Extenders continue to sit at 0/1 for both Polymer and Electronics, and the health of all structures being tended by those buildings continue to degrade.

I think it's the Maintenance screen that is causing problems. With having tier 3 on the planet, the Maintenance view doesnt function correctly. Almost like the game doesnt understand what is going on.

Ran into a bug with the third tier of the Power Extenders. When selecting the third tier to place one, the play space locks up (not the UI but the planet interface). Fixed by selecting ANYTHING else to build. Can upgrade 2nd tier to 3rd tier with no issues, so at least there is a work around.
