Ok, @AlphaWolf 25,
I got an error, but it seems to be due to a conflict between Heavy & Superheavy Mechs and Rebalance Mod, since Heavy & Superheavy Mechs already includes the latter.

The creator of Heavy & Superheavy Mechs himself writes:
```
Includes Rebalanced changes as default, thus DO NOT USE AT SAME TIME WITH REBALANCE MOD.
```

I also tested Heavy & Superheavy Mechs a bit with my EZ difficulty and didn't get any errors, but they are possible since I changed balance.ini:
```
This mod is unlikely to work with any other mod that changes balance.ini. May break with future updates, uses unsupported features to implement dual reactor mechs.
```

Bottom line: just uninstall Rebalance, it shouldn't change anything in the game, I think you can continue playing on the same save.

P.S. also don't forget that the EZ difficulty mod should be selected last (at the very bottom when choosing mods).

I hope it helped. Good luck!

Hi, @AlphaWolf 25, I tried to recreate this error, but I couldn't.
Please send the error content here.
Also, do you use other mods, do you get errors when doing other things?

hey so i have this mod on my game and any time i try to take a weapon off a mech in the production panel the game crashes
