When I drop an item from my main hand with its enchantment boosted by the resplendent prism, the enchantment bonus remains on the item (When i drop a sword of sharpness I boosted to sharpness II by the prism, i pick up the sword as a sword with sharpness II boosted to sharpness III by prism). This resulted in infinite stacking of enchantment levels.

This is a mod interaction. Please try binary-searching through your pack and see which interaction causes that.

AS version, forge version, modpack?

Running the latest version of AS and forge, playing on a custom self-made modpack with some rather old mods, the bug didn't occur with some mods removed. But i don't have the time to find out which specific interaction it is so i will have to deal with it for now

I suppose it is caused by some no longer updated mods since this bug didn't happen when i was playing another modpack with all constantly updated mods
