This issue is not game-breaking but strange and I encountered it for the first time. So I decided to share.Bell 47 helicopter.
I found and downloaded some cool skins for this wonderful creature. Placed them into the appropriate folder.
Made the new mission where Bell 47 was used as AI and also played by the pilot. New skins worked in all cases.
Then I tried the same mission in the Multiplay...
Started the server, launched the mission, pressed the Arming button, selected Aircraft: Bell 47, Skin dropdown list...only "Default" skin was available.
Uh-uh.
Selected other aircraft - their many skins were available. All skins were stored in the same /Skins directory.
And while the mission was running in Multiplay, AI Bell 47 choppers happily flew with the customs skins as I designed in FMB...
Smells like an AI conspiracy to me.
So, in a nutshell.
Customs skins for Bell 47 are not available for the player in the Multiplay.
Note: I use one "centralised" storage on the external HDD for all skins, with symbolic links to all versions of IL2 1946 on PC. I created the links once again but the problem persisted.
As said, not a big issue.
But if someone can check and replicate this problem in Multiplay, I'll be grateful.
If not replicated, my suspicions about AI conspiracy will be confirmed!
