Setting an active object (opening properties pane) in the map editor while another map editor tab already had an active object caused corruption. Now the active object is deselected whenever the tab is changed.

This issue has been resolved.
Numbered Steps to Reproduce Problem:
1.) I viewed an instance https://i.imgur.com/QcHU1PA.png
2.) I switched to a different .dmm file, viewed a different object https://i.imgur.com/mVHq2ox.png
3.) I switched back, now the object has been replaced by the object I viewed https://i.imgur.com/N4t184U.png

Code used, the .dmm's are there for you to test with:

The BYOND version I'm using is also 515.1627, posted in the wrong sub-forum
Can you expand on this with the exact locations and instances you worked with? Your numbered steps are overly broad and with map editor bugs I need absolute specificity.
Open 01_Meranthe.dmm
-> 719,519,1 dark_out -> Make Active Object

then open 12_Arenas.dmm
-> 65, 962,1, Dark Rush Dungeon -> Make Active Object

Tab back to 01, dark_out has now been replaced by Rush Dungeon Object

This should be Dark Rush Dungeon but it's now dark_out after switching between the files/objects. Nothing was edited within the instances, just interacting with them https://i.imgur.com/br3t0Hd.png
