Started a new campaign this afternoon, after I had to adandon my Prussian one due to the weird corruptions and the constant CTD's on loading my saved games.
However, despite limiting the Mods I am using to just TROM I still found I had the weird 'flying saucer' effects for the cannon balls. (see below)
This is a test battle I set-up specifically to test and isolate the cause of the problem. This is with the game running with the trom_blood_smoke and trom_battlesounds ticked in Mod_Manager.
Below is a re-run of more or less exactly the same battle set-up, but with trom_blood_smoke and trom_battlesounds unticked in Mod_Manager and BSM_3_1_FULL_all_cannons_MM and weaponFX ticked instead.
Its pretty obvious that something in my game doesn't like the TROM version of these blood and smoke mods.
The only other thing I think might be worth mentioning, is that I have absolutely NO interest in the Warpath Expansion, and so haven't bought it. However, at about the same time as these strange coruptions started to occur, I also noticed that the indian's in my campaign started making speeches (using really bad voice actors, trying to minic native american accents), make pathetic whooping noises when running, plus a rip off of the train sound from the film Zulu when walking.
So, I'm thinking that whether I like it or not I've been given at least part of the new content from the Warpath campaign (e.g. the naff bits), and I wonder if the fact that I haven't bought the whole package is screwing my game up.
