UPDATE FIXED!
For anyone else having this issue. If you 0 out an entire loot table you have to set the probability to 0. If you dont it makes the zone try to load said loot over and over and the zone will not load and timeout/crash. Don't know if this is a bug or what. But that is the fix.
The odd thing was after a revamp on crushbone we did the same thing with no issue. Once we did nektulos thats when the issue popped up it seems more like a bug to me. With probability at 100 and all the loot in the table set to 0% seemed to tick it off.
