Glad to know its not another one where its intentionally designed that way. However, it does not appear to exist for the **mobile** (android) version
im not seeing it. I checked there already (before commenting the first time) and clicked each option. The closest one was a "<" and that just opened the history log.
Edit:
Re-downloaded the game to check again. I can confirm none of the options that display do a rollback. There's 'collapse', menu, auto, history, skip.
I'll go ahead and remove the review though since this wasn't intentional and I assume you will fix it. I get that mobile probably isn't what you develop on so its an easy mistake to make. Likely a mistake when you made the custom menu.
