Hi, thanks for commenting. Will check out! Let us know if you figure out more.
I also noticed this same bug on the Sandbox, Experienced, and Expert difficulties as well, with the Sandbox difficulty having it occur on a different set of tiles, but in a similar location.
I haven't been able to reproduce this but we have a new build upcoming that has a lot of bug fixes so hopefully it's not a problem anymore.
And thank you for letting us know! Will do some extra testing to make sure it's fixed.
