@Uveso That's the best news I've heard in a while！ I will test it soon, thanks for your great work, best wishes!

@JamCrumpet I'm sorry that I didn't solve your problem, but I still need to explain it further.
As I mentioned at the beginning of my post, the latest v13 version of the RK-s-Explosions Mod needs to be downloaded from the author's github, not moddb, and not faforever. my solution is also for the problem that exists with v13, not v12.

@ZBC
Hey ZBC,
thank you so much for your hard Work to bring the classic Firey Explosions Mod to FAF.
Looking forward for upcoming Updates and you own Explosion Mod in the future.
Keep Up the good Work.
Best regards
CDRMV
