No issues so far here, though maybe different situation?

I've yet to have any issues, force close or otherwise,using that same TWRP 184.108.40.206 for backup and recovery operations, though I'm not sure how helpful that information is for your issue given that I've only ever restored basically different versions of the R.D.D.T v1.0 and 1.1 ROMs, albeit numerous different times, at this point.
Incidentally, over the past week or so I've also been giving -75 all around for voltage a try without any apparent instability from that either (knock on wood) so that's been fairly cool to see our phone can hopefully manage as well, at least as far as I've been able to tell so far.
