This is very annoying and makes the game not playable.

If you go down this forum, different crushes happened.

For me, it crashes when re-entertaining a big vault with a lot of collecting. May be the game Cannot handle that much.

One interesting thing is that if going to the shop before collecting, everything is fine.

Not to be a spelling nazi, but I think you mean "crash".

Yes, that should be crash.

Must be doing too much "rush"
