I’ve been having a few freezes when messing around on M10. Those only occured after knocking it up to M10 and stopped happening after re-rolling the modifiers.
The Modifiers I had during the freezes were:
1: Big Kick Energy (increased damage, increased recoil)
2: Mob Mentality (enemies that are close to each other receive a damage boost)
3: Chain Gang (Enemies are linked with damaging beams)
4: Holy Crits (increased crit damage, decreased non-crit damage)
If you are experiencing crashes, check your modifiers to see if you have rolled one or several of these and try out whether re-rolling fixes it.
