I tried loading "Always Win Coin Tosses" with your mod loader, so i deleted the .js file in plugins and put it in the "mods" folder, of course I edited the "TY_ModLoader.js" file too, after that I made a new game and fight August at the start to see if I would win the coin toss,
as expected I failed the coin toss.
So I'm starting to think that the problem originates from making the "TY_ModLoader.js" file work BUT HEY THAT'S JUST A THEO- anyways...
When I wrote days ago, the only mod I had installed was the two I mentioned, Right now I have "RPG Maker MV Cheat Menu Plugin" and I don't think this is an issue
So probabily tomorrow I'll try reinstall the game and do everything again, and hope that It would work. If not, I'll add you on discord.
