I wonder if just commenting out that line 40 in res\config\game_script\mn_upgrader_gs.lua makes the mod break and stop working as intended:
game.interface.setPlayer(param.id, game.interface.getPlayer())

But doing so helps with the issue.

That seems to work, see

Hey! Are you certain that this works? I attempted to comment out the line, but I still get this.

Hmm. You used it in a game where you created the map beforehand and placed the industries manually in the map editor?

It was a premade map that I downloaded from the workshop, but it was a "self made" map beforehand if you can look at it that way.

I will test it in my next game session, perhaps the behaviour was changed again with the latest patch - and I did not use that mod on industries since then. Only on train stations.

Hmm. On my end it looks like there is a little impact, but just like 10% more of "infrastructure/misc" cost instead if the ridiculous values it was before commenting out that line.
btw I got a lot more industries, with https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1951335527 and https://www.transportfever.net/filebase/index.php?entry/5470-power-stations/

Ooh interesting, im gonna try that one, thanks!

@GordonDry, In Senseless V2 I've lowered the maintenance costs for manually placed industries considerably. I will update V1 also. ;)

And I updated this as well:

@Yeol:
I see you found a better fix, as addon mod, with a slightly different approach than just commenting it out:

Causes my game to crash when loading with that mod on.

@wncol2004:
Not here. May game got 800+ mods and does not crash.
Your issue is elsewhere.
Did you realize that you need both mods as the mentioned mod is an addon mod to the original mod?

I figured it out. I missed the small section of keeping the old mod and setting priority higher on the old mod before loading his mod. Works great.
