well, i found myself with some weird tilled milk in my inv, no idea how i did actualy got that, but whenever i try to add it to a chest minecart, hopper or anything else my game crashes (appart from the ME system cause it simply dont accept) , so i was wondering if that was worth asking support for or just trash some milk away.
I would just trash it, if it happens more than this one time, staff could look into the cause. did you remember if you had anything in these slots beforehand, and did it happen while you played on the server, or did you just join and they were there?
it happened while i was afk and no i didnt had anything on them (the inventory spaces that got milk in it)
