I did a "clean install" of Fabric Loader, Fabric API & Improved Fire Overlay - it crashes on startup with the following error.'

Strangely, the mod starts without problems when I install Inventory Control Tweaks as well. Accordingly, I can actually use it, but I couldn't get it to run without it and just wanted to let you know. I have absolutely no idea why, but it is very strange.

I hope this is helpful, if there are any other questions I will of course try to answer. I hope this helps.

The mod also requires mod menu to run, try a clean install with that and it should work. if it still doesn’t, just reply to this message.

It still crashes

not sure if it is the exact same error tho. - Inventory Controll Tweaks seems to fix the startup problem for some reason tho.

Nevertheless, I think it would be quite practical if the Mod Menu were described not as a recommendation but as an actual requirement.

I hope this may help to find the problem

With kind regards

Fixed in v3 of the mod
