TDW's Ship-plane fire damage v1.3 SH4
I used it... in earlier on incantations of FotRS-U EN... & with a couple of other mod sets...
without any issues, that I knew of... except for, mhmmm... think it was with v1.46 of FotRS-U, with a ship or 2... refusing to take damages, at all.
That said...
am with propbeanie... but... should you choose to accept the mission...& add it in, would recommend, making a backup copy of your save folder... prior to adding it in... just in case.
That way, if it has... adverse effects, can always dump that save folder with it added in & revert back to that backup save folder copy.
