How to Stop TML from Re-downloading Mods I Unsubscribed and Deleted?

I delete some mods in TML and unsubscribe them on Steam Workshop, but they keep getting re-downloaded whenever I restart the game. I've double-checked that I've unsubscribed from these mods on Steam Workshop, but the problem persists. I’ve tried deleting these mods multiple times, and each time I exit the game, they are automatically re-downloaded when I launch it again later. My questions are:...

Bosses have WAY too much HP for me to reasonably kill them.

While using the modpack I loaded in the log, I noticed that the Eye of Cthulhu has almost 9000 HP in expert mode. I checked the other bosses in cheat sheet, and they also have at least double their normal HP.

Is my issue a result of the HP scaling of tModLoader with 200 mods, or am I stupid and missing a scaling config (or a mod that massively increases HP)? I wa...
