Delete your old version, if you had one, then put this in the same place.

• merged mutations should only show up once per run and be guaranteed unique
  • the code's kinda ugly though
• added new options
  • the number of maximum weapon pickups and rads can be changed to help combat lag
  • a maximum distance with HP and ammo pickups is available, they will disappear when too far from a player
  • USE THESE OPTIONS AS A LAST RESORT FOR SOLVING PERFORMANCE HITS
• updated fake mutations.mod.gml
  • mutations should no longer draw on the credits and win screen
  • added fake_skill_exists(skill)
    • checks if the skill is present in this mod's storage and it's a lightweight object
  • improved how mutations are selected
    • modded mutations actually get a chance now (I didn't test the old version)
    • Defpack 4's prismatic iris should no longer be broken
  • level generation should no longer change while this mod is active
  • skill events are now handled by the regular step event instead of a CustomStep's
• updated fake crowns.mod.gml
  • custom crown selection with /fcrown should be better
  • added fake_crown_exists(crown)
    • it's like the other one, but for crowns
  • further improved crown train support
    • crown_take gets called on selection instead of the next level, so cool
  • level generation should no longer change when this mod is active
• mutations persist better through mod reloads
• mutations get reset internally every run
• mutations are now generated in chunks
  • if you start a run, the first level up screen will have a slight lag spike
  • from then on, the amount generated in the chunk is 28 - existing amount
• gamma guts can more reliably hit things
• gamma guts' blast doesn't scale anymore
• strong spirit can't replenish if you started the current level with full HP
• patience-related things should be more reliable, maybe
• crowns persist better through mod reloads
• crowns get reset every run
• the position of the crown that's all crowns at once should be constant
• crown of destiny no longer waits for the next level to give a mutation
• crown of death now copies explosions instead of creating them again
  • ever see an elite shielder fire green plasma?  that's fix
• crown of guns drops guns occasionally from Throne I, Throne II, and the Captain's large projectiles
  • might help prevent softlocks?  some crown combinations are still doomed
• crown of love no longer replaces portal strike canisters
• loading tips are better now because they still combine when there's more than one base tip
• updated custom options
• various fixes (and new bugs) I may have missed

If it doesn't work, let me know.
