Same problem over here. 2 accounts with Tormin and Trunda/ Tormin and Tyrant Ixlimor - every second attempt to run it - game crashes and I get a message that there was an error ... 

tested without freeze/burn combo - works fine btw

Don't have a consistent success rate without this team. Already wasted enough energy, I can't be the only person that's not going to be able to compete for the rewards due to this.

I missed the Fire Knight fragments by ~20 due to the long standing AI issue of not removing unkillable even when you have buff strip in the team. Venus / Cupidous and Ma Shalled both wouldn't strip the unkillable so the game just hung for hours each time. Would have been first by a lot instead ended third by a tiny amount when I had loads of energy to use.

This is the type of stuff that puts people off the game and never spend again.

Hello op

would you be able to provide a recording of this happening so that I can forward it to support, thank you

as far as freeze related issues the devs are aware of them and working on a fix. however I think this one is different as its crashing the game rather than just lagging from what im reading here.

thank you

Depends on what you mean by lagging. The game doesn't lag, it has a window stating there was an error giving you an option to click yes /no on reporting it to the devs. Clicking either one takes you to the bastion(?)

So not crashing the entire program, but that's not lagging either. Multi battle or continuous replays error out, so maybe saying crashing isn't accurate, but it's not lag.
