Double loaded mod files

In this example I changed the AI names for a modded AI (AoModAi) in a new mod with higher priority, but the program created the entries twice in the selection list.
It means that it had been loaded twice despite of the identical file names (aomxai001 AoModAI, …)
It seems that the mod with lower priority forces to load the identical file from the mod with higher priority one more time.
