that may save both In-Game memory usage and over-all Drive Space when considering the Bigger Picture.
Issue:
There was a time when the Tile Editor would save Tiles and then when they were re-opened, all of the current objects that made that Tile would be duplicated exactly, thus creating bloated Tile in both Item count, as well file sizes and perhaps even unnecessary graphic load issues.
Example:
(Randomly selected for this Post - corrected other(s) exhibiting the same symptoms. (How many actually exist unknown)
Load F_Outpost_2 (count items on the Bar (across the top) Count is 120 items.
Now delete all the (duplicated) extraneous items and Save. Count is now 54 items and 3K file size reduction.
These files have been like this since Beta .01 until they actually fixed the Editor but it appears the Dev never went back over the original Tile set to correct the issue. There is no way (other than manually) to know how many in-game Tiles still possess these extraneous items internally but it couldn't hurt to actually find and clean them ALL.
It seems about time for a E:WoM cleaning Pass before moving on to EF.
