I am setting up 1.10.2 development for those mods now, will hopefully get this fixed shortly, until now I have just been developing this for 1.9.4 and it has been working fine in 1.10+

Uploaded 4.0.0 for ThutCore to curse. it fixes this issue.

that's mainly because Forge didn't touch any of the core classes you were using up until now. You can chat on my chat server so as to not needlessly clutter your issues if you want to.
