@KirbyMirror2 I finally copped the update that removed roc_md500_asw but in good news I've managed to replace it. Try now and let me know how you go.

Yeah I just updated myself and tried again. It is still working for me post upgrade. That particular helicopter is a tad different in the game files to others as it doesn't appear as a .ini anywhere but it's in the source. It's the only one of those models like that as I really like the radar and MAD equipped on effectively a little bird.

Did you check in the mission editor to see if it's listed under the US? If it's not there might need to repair game files/reinstall?

@Hoovercopter I am stable #117. The only mod I have installed with roc_md500_asw is YANG class MOD III. I don't have that enabled. Also, the vanilla game files do not have an roc_md500_asw as of the latest build. I don't see anything else conflicting.

If you check the mission editor roc_md500_asw can be found under the USA, not Israel as the MD500 ASW (Helicopter). Have a go checking to see if you can find that helicopter, if it's missing then it's probably a clashing mod.

Another step to try is to put this mod at the top of your load order and try again. It sounds like something else has changed the roc_md500_asw file.

Hmmn, I just tested it again on version 0.1.0.7 Build #108 (15267) and can't see any issue from my side. Is it still a problem with other mods turned off?

Which ship are you launching from or is it just in the mission editor?

@Hoovercopter When I use this mod, I have the following error in my logs:

[General] ERROR: KeyNotFoundException: The given key '(aircraft, roc_md500_asw)' was not present in the dictionary.
