imported fbx mesh, cannot rotate in Z

i have a very strange problem, i have a mesh in blender and when i import to unity as fbx file, it imports ok, and in the inspector i can rotate in X and Y fine, but rotating in Z rotates it visually in Y, although the inspector claims its rotating in Z

any ideas what could be going on? i’ll include the .fbx for ref

its the parent that isn’t rotating, the child ‘deck’ seems fine

thanks

i think this problem started when i hit the ctrl-a key in blender to apply object mode scale and rotation changes but when i look in blender, i can’t see a problem.

i have found that after i do a ctrl-A on the whole model (in blender), then in object mode, i rotate one of my child items (cannon barrel in this case) then i export it as fbx, then it all works well again.

no idea why, but its a fix
