I don't understand the cause of this issue, and it doesn't seem to be caused by the mod—at least not by mine. I can make a reasonable guess: it might be related to High FPS Support. You can try disabling it. However, I recommend first disabling all mods and then restarting the game to see if the issue resolves. If it doesn't, then it's likely not caused by any mods, and you should consider submitting an issue post to the TML developer community or seeking broader assistance from the Terraria forums community. If the game works fine after disabling all mods, then it's likely that one of the mods is causing this unexpected behavior, and you can then check each mod individually.
