How Can I stop my oppo A3s from deleting my games cache

[Android Central Question]

My phone is oppo A3s and it keeps on deleting my game cache, the game is the walking dead road to survival, every morning when I check my game it's been erased, It only happen on that game but not in others, the app is still there but the cache had been erased, Anyone got ideas to solve it

Are you closing the game? If so, it's supposed to delete its cache. The "solution" is to leave the game running and the phone on all night.
