Summary: Whenever we delete a region file and restart the server, it appears that a majority of the trees duplicate. Then when players visit that region the server becomes unstable and hangs up within about 30 minutes.

Did you wipe old saves? No. We are using the map from build 323 that we built a few hours before 324 came out. We had this same problem on b323.
Did you start a new game? Yes, on b323 and continued on with b324 in the same world.
Did you validate your files? Yes
Are you using any mods? Yes. We are using Alloc's Server Fixes (newest release), and CPM 23.3. We were able to replicate this bug on a fresh world in b323 without any mods installed.
EAC on or off? ON
Bug Description: Trees duplicate in a region when the region file is deleted and then the game regenerates it.
Detailed steps to reproduce the bug:
1) Visit a region
2) Shutdown the game
3) Delete the region file
4) Start up the game
5) Visit the same region again and look at the console
6) Move to the coordinates of the "WRN AddDecorationAt"
7) Chop down the tree and find another inside it
Actual result: The game is duplicating all, or at least it seems like, all of the trees in the region
Expected result: That the game would clear the decorations database for a region that was missing and has to be re/generated.
We regularly delete region files to refresh the game tiles because we have so many active players that the map gets decimated in a day or two otherwise. We've been doing this for the last 5+ years and A21 is the first time I remember this issue happening.
