Minecraft version: 1.12.2
Wizardry version: 4.2.5
Environment: Singleplayer

Issue details: It would seem there is a naturally generating object that is causing a client crash as soon as generated, leaving various areas in player worlds left untouchable. Although the crash log is leading me to believe the issue is caused by some form of dispenser, a mod conflict issue is also not out of the question, for I had many others installed during this particular session.

This must be jungle temple dispensers, they sometimes generate with scrolls and other dispensable wizardry items in them. I don't know why this is crashing but you should be able to work around it by removing all the items from the loot table ebwizardry/loot_tables/chests/jungle_dispenser_additions.
