Playing game like normal
After aprx. 15min of game play and general after mining continuously for at least 5min. The error starts to occur.

will mine either a single block or a series of blocks, they will break and drop collectibles, then will reaper in place, collectibles disappear, I can then re-mine them, it will take three or four attempts at mining before they break and stay gone.

Only way I have found to clear the error is to save and quite and then reopen world however this only works twice then have to completely close program.

The problem seems progressive the longer I play with the error the worse it gets, eventually massive delay becomes present when placing items.
