Crashing game/client when using flux storage containers in a tinkers table (drag dropping/splitting item stack)

crash-2019-04-24_20.49.23-client.txt

Sky Factory 4.0.2
minecraftVersion": "1.12.2
forge-14.23.5.2831
Mantle-1.12-1.3.3.49
TinkersComplement-1.12.2-0.4.0

It can be reproduced definitely on SkyFactory 4.0.2 (not sure if other mod pacts are required IE, if reproduceable with just fluxnetworks-1.12.2-3.0.19-21 and TinkersComplement-1.12.2-0.4.0 just by them selves)

So this just started happening today, deleted mouse tweaks mod and had this to say. Playing the pack Sky Factory 4.0.2.
In my inventory/extended inventory/crafting table inventory i have no issues, i can reproduce it multiple times when i use a tinkers construct crafting table (i was testing it with the slab tinkers crafting table and have yet to try with a normal tinkers crafting table) with flux storage containers.

With some trouble shooting, with some admins and myself it seems it might have to do with something with flux storage containers and tinkers work tables not liking it, as well as some other items (not sure which) and the items rendering in the crafting table? but it is confirmed that it involves tinkers crafting tables and flux storage.

reinstalled the newest version and got this

The game crashed whilst handlemouseclick() threw an exception when called from mousetweaks.
Error: java.lang.reflect.InvocationTargetException

Already looked at and through the mouse tweaks Github.
YaLTeR/MouseTweaks#15
They seem to imply that its not mouse tweaks but either flux storage or tinkers construct
