Recent crashing issue of the game has been very abundant this week. Post update. FORTUNATELY, gumi promise to fix it this week so rest easy but for those who have been trouble lately, here what i found out (from personal exp and from what i read)

1. It happens more frequently on ios devices
2. Crashes happen when you use the JUMP ability by kain
3. Crashes happen when you have a status ailment at the end of the battle (this is the most apparent cause, esp if you have the blind ailment)
4. In boss battles, if you crash mid-way or at the end of the battle, you have a chance to play at mid-way or worse reset the whole boss battle, this becomes troublesome if the boss can inflict status ailments. So tip: if you can cure the ailment before killing the boss, do it.
5. Its more apparent in exploration quest. This is the most cause for concern, i frequently crash 4-5 times in a single run. But that's mostly due to the fact the i have a status ailment! So cure it frequently.

That's all!
