I think the added tiers are causing Hextorio mod to crash due to so many quality tiers... so i hope one day there can be some compatibility with that one

This incompatibility is probably happening because Infinite Quality Tiers Plus can use up to the game's quality tier cap, which is 255. I think Hextorio adds 3 more quality tiers, so try reducing the number of quality tiers in the Infinite Quality Tiers Plus config.

If it still crashes, please send me the log and I’ll gladly try to fix the compatibility issue.
