That never happened to me before! I even tried to replicate it here. Sorry. Maybe you could make a gameplay video of this issue! would be nice for the developer!
I don't recall a bug like this happening when i played A4. Not even on A5 it happened either though. I don't go trying to replicate bugs that people already found, but when any kind of bug happen, first i look whether someone already post it, otherwise i create a new post.
