Hi icry4u,
Here is a breakdown,
Previous iterations of 1.12.1 (it also works during 1.13.1) have the problem of concluding the game as LOSE even though it was won for the following game type
Kill all enemy (in 20 turns) and Silver Dungeon
it works fine for all other game mode
The latest apk at 1.13.1 will crash after the turn is over, you have to complete the game within the turn, the game will successfully complete (including Kill all enemy in 20 turns game mode[it has to be a small map though]) .
I was using 1.13.1 obb after installing both 1.13.1 or 1.12.1 modded apk.
As with the latest update from playstore, 1.13.1 and 1.12.1 apk will not proceed.
Thanks
