If the fuse caused the flingring to be deleted, it would hog a spot on player->pickuprings until the player respawned.

This is not a perfect solution, but it should resolve the problem in practice.

Needs testing to confirm this doesn't introduce TA desync, but in the worst case I would wager it affects a single digit number of runs at worst.

M_BuildConditionSetString: Show a more tantalising message for Challenges with forbidden descriptions

"(Find other secrets to learn about this...)" - this replaces "???"

M_DrawChallengeScrollbar: Fade to white based on the % of challenges unlocked in the column, not the raw count

Means blank squares won't cause this to be permanently incomplete

Avoids dereferencing ref->conditionset, given ref can be NULL for blank squares

Forbid character-based unlocks if you switched your skin in a context where it didn't auto-spectate you (more robust stop for #1231)

Nah, ballhogs will eventually have the same issue despite their delay. Moved x3 orbi & x2 sneakers back, increased singles of those.

Removing quad orbi & triple sneaker odds entirely, added some ballhogs instead.
