Add "EcmSaveFtreeToDisk=0" to prime.txt. Looking at potential issue right now.

Okay, have done that.

Cant tell if a coincidence or not, but almost immediately:
M84391 has a factor: 98209937594996429644713680314663065731663 (ECM curve 34, B1=11000000, B2=45026771790, Sigma=7902727148730402)
Group order factored: 2^6 · 3 · 47 · 359 · 521 · 3221 · 39079 · 1615351 · 8927143 · 32056094767 (barely inside both B1 and B2)

136.2 bits.
