@The King'S Works Just because you and your fans want to use said mod, which I'm pretty sure is not even yours in the first place and avoid using SCS MP, it doesn't make sense to generalize. Most people just enjoy the platform as it is, even without mods. TMP is a mod too, remember? It's crazy to see what they've achieved in the last 7 years, yet you're here to complain about some little unofficial addition to the game..
The optimization topic has been discussed a lot before, it's not TMP's fault as far as I know.
Players leaving TMP, is not caused by this, but by life slowly returning to normal after the pandemic.
I'll end this nonsense of complaint of yours, by saying that if TMP blocks something because they think it can cause issues, beat it.
