As the tittle says the new version of create crashes the world as soon as a fan catalyst is loaded. dont have a crash log of it but from what i read from the crash logs (from curseforge) the game "cannot find recipe for fan catalyst-" and lists all catalyst types. upon turning off every machine with a previous version of create and re-launching the world in 6.0.6 it still crashes, tried the same with removing all items from belts infront of the catalysts.

ah, fair, my bad for missunderstanding, gonna close the issue note just gotta add that I love this add-on. Half my machines would break without it

The recipe errors are unrelated because Create 6.0.6 introduced breaking changes requiring some addons to update, including Connected. I will do that as soon as I have time.

i went back and got the log, it starts after the world is loaded so i copied it from there till the game saves the world [12:36:10] [Render thread/ERROR]:Could not find a matching ingredient to remove: 1 fan_seething_catalyst create_connected:fan_seething_catalyst

I might have missunderstood something (i obviously dont code). i tried temporarily disabling other mods that loaded during this time like journeymap and essential but this was more or less the same exact log every time

i forgot to add that i managed to confuse recipe with ingredient but i'm sure thats clear

I'll need a crash report to know what's happening, because recipe errors normally do not crash the game.
