What bugs/issues did you encounter:
What is your FM version: 19.3.5
What is your FMRTE version: 19
Which operating system are you using: Windows 10 Home
FM Version: 19.3.5
FMRTE version: 19.3.5 (I have used the update feature that says I am using the current version)
Beta Testing: No
FMRTE as Administrator: Yes
****I am not sure whether these crash dump files created by FM19 are what you want or what you need to address this, but the FMRTE application is not what is crashing in this instance. I have attached the crash dumps created by FM19.****
I am attempting to add North America to "Nations Treated as EU" or "Nations Treated as Non-Foreign" for Gibraltar. After I add Continent -> North America to the drop-down on Gibraltar's page in FMRTE and save, I can confirm that it has taken effect; all my players from North America no longer have the red WP indicating that they do not have a Work Permit. The game will allow me to advance normally with no problems.
However, if I try to reload a save from before I made the change, FM19 will encounter an error and crash. In my own trial and error, I have discovered that this only happens the very first time you try to load a different save; when I crash out and launch FM19 again, I can load both the save with the edits made and the save from before edits were made with no issues. I can also load the saves back and forth with no issues.
I believe I also confirmed that it does not matter whether FMRTE is still opened and hooked in to the application when you attempt to load the older save, as I reiterated the same steps, but closed out of FMRTE before attempting to load the older save and the error persisted. I have attached the second crash dump where I closed out of FMRTE before loading the older save for completion's sake.
I have notifications turned on for this post so I will attempt to answer any further questions you may have.
