takeitem mechanic does not work on latest dev build (MythicMobs Premium 5.4.4 SNAPSHOT Build 4829)

The title is self-explanatory. The mechanic was working fine until I updated to the latest dev build. No errors appear on console when reloading or using an item/mob using takeitem. The code was not changed prior to updating. While takeitem stopped working, giveitem works perfectly fine.(Update: this seems to concern mythic items only after some more testing and this issue affects all recent dev builds/versions).
