[0.91.9]Nav redraw ceases to function. cannot enter building

[Zeal]

I keep having an issue where all my buildings become unenterable. Anyone who happens to be inside a building, who moves, is instantly spit outside of the building, and cannot re-enter. At the same time, the navmesh shortcut ceases to function. Pressing the hotkeys does nothing at all.

I had this as well.
I saved and reloaded and everything was accessible again.
But nav mesh redraw was still on the blink.

happens with me twice today to - first time after i build small house(just cant enter it at all), second time after restarting game client
save-load or just reload save game fix that.....

Same here. Doing said above fixed this issue. Just save and load the game file.

More then that, actual button found in Ctrl+f12 menu doesn't seem to work either.
Had this issue couple o' times, reloading saves And once my storm house got half buried underground after importing: swampy terrain, i guess
