Windows .exe FTB Unleashed Crash when Opening Smeltery GUI

[Kaistau]

Well, I don't really know what to say, other than every time I try to open the Smeltery GUI from Tinkers Construct, my Game crashes.
The most recent crash report file is attached for reference for support.
Any help would be much appreciated.

P.S: it only started recently, it's been working fine up until yesterday.

Did you do anything right before opening the GUI the first time? Like place down a block/entity? Also, have you tried breaking and replacing the controller, or moving the smeltery altogether?

Thanks for the Attempted help, but before i saw any other posts on here, i just emptied the smeltery and that seems to have temporarily fixed the problem.
Also, no I did not place anything down, a had an empty hand when trying to open the Smeltery controller.
if I come across the problem again, I will be sure to post in this same thread again.
