After SU5 textures seems to be picked sometimes at random from other folders containing AI simobjects - it can be from simobjects in the same package or across packages placed in the community folder. I can only confirm it to take place with models based on mdl files and only between boats, but users reported that there was also interchange of textures between boats and airplanes.
The same add-ons worked before SU5 with the same file structure. The problem also appears for some users when they have addons referencing the AI objects using them as static objects. The object might display correctly during one flight and during the next have the wrong texture.
Example of simobject with texture from another simobject
Did anything in the file structure or package compilation have to be changed to avoid this after SU5 or is this a bug?
