Ok crash is after load save when saved in cryochamber. Mayby that help. If load save in free space all good but break after save in chamber. Crazy thing.

I threw in some checks, it 'shouldnt' happen again, and you'll see an error message instead. I havent been able to reproduce, or get the messages. If you do, please let me know what it said, it will either be "NO SUIT DEFINITION FOUND YET?" or "NO OXYGEN COMPONENT FOUND YET?"

Ok i test it now.

All work , save is repair and no error message. Thanks for fix :)

Hi. Have crash again after load save , this is log last words :

Try loading again, I've occasionally hit this but I havent yet figured out why, let me know if it continues after another load attempt

All saves crash in 5 min after load. Dont know what to do that but in log last type is hazards info :) I em playing today , and after back now to game all saves have this crash. All work good before so "wtf" ? Dont have any clue what is wrong now with this game. Dont instaled any new mods so all are same mods. But nanobots (BuildandRepair mod) weld some new grids , mayby that cause this crashes.

I'm not sure it will fix it, but I just uploaded an attempt.

All look fixed , Thanks again :) Game work.

The above exception occurs every time I try to create a Reactor (any kind)

Unfortunately, I havent had time to test in multiplayer; I'll need to have a look into this and see what I can do. Is this crashing the server or the client?

@ValkoDragon - I've fixed the crash, though I did find some other multiplayer issues. I'm going to try and sort them out

Hi. This mod https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1365616918 dont work after new Hazard update , before all works :) Tested this two only in world.
