Falling through the map homecave

When I first log in or enter the home cave, and then leave the home cave my playable begins to fall through the map.

When I leave the homecave a load screen appears and afterwards I begin to fall; then another load screen reappears and I’m out of the homecave in the area but sometimes my playable will die. The playable will die not lose growth but only marks. The death is a rare occasion but falling through is inevitable

You just leave the home cave no two load screens or death (rarely)
