Mods dont work in 1.4.5

Hello. I wanted to add some mods to my game, but when I added it in, it doesn’t have any effect.
How do i make them work? (P.S, they are not ultimatelib mods)

If you could provide links to the mods that you used, that would be great. Even though UltimateSuite is buggy, mods that aren’t reliant on it can be incompatible due to poor coding or insufficient updating.

well, i tried the platform randomizer mod.
