Attempting to put some molten emerald into a casting basin via a Mekanism basic fluid tank, causes a repeating crash until the basin is emptied or removed. I reported it to TConstruct first at SlimeKnights/TinkersConstruct#2849 but they said the problem is related to Mekanism rendering. So posting the issue here too. For anyone else that's had this issue, they also gave a workaround to temp fix the crashing.

Please use the search function. This is reported multiple times.
Aidan is looking into it, but can't find anything yet. I'm also looking but still no clue.

See #4212 (and many other issues)

I did search. But I only searched the open tickets. And I apparently searched for the wrong keywords. Sorry.
