Hey guys.
As many of you figured out, the base cause of this was some fixes to base raidable checks. Previously, items on walls were not properly blocking off space. Now, any item on a wall will count as obstructing the entire column of space it occupies, to prevent inaccessible rooms.
We didn't intend for this to delete doors between rooms, or make a base uneditable. Those are bugs.
If you have a problem where you can't edit your base, you should remove any wall items, or move them to out of the way places. This is especially true for anchors. Then, have everyone leave the base for about 5 minutes so it will restart. When you come back in, you SHOULD be able to edit your base again.
If this doesn't solve your problem, please /petition it and a GM will be able to come help you. Also, if what I said above doesn't work, feel free to post in this thread and explain your situation, so I can check up on it.
