Quick update on the Bronzelock Pistol issue: it is only occurring on mobile. I am using an LG G6 running Android Oreo, X4 animation speed, low quality, power saving. On my Win10 PC w/ 4.0GHz quad core, 16GB ram there is no issue and I cannot replicate. On the mobile device, it happens with higher levels of gem destruction, seems to be consistent when >70 gold has been collected. I did try a full reinstall of the game, which did not fix the issue.
