Inaccessible Buildings

[mk_thot]

So I've been having issues where characters can't seem to enter buildings at random. They can get right up to the doorway, but are unable to actually step inside unless I use a second character to pick them up and put them down so they land inside. This happens with both normal buildings and ones that are destroyed. So far, this has been happening most commonly with the bughouse (for me anyway), but I've seen it once with a longhouse. The fix I've found for it yet is to just save and reload and everything is back to normal.
