i had a premade anti plasmid for jump boost waiting for this update. i know it was said to have been fixed in 1.22 but as it was stated that mutation calculations were being fixed in 1.23 i skipped 1.22

anyway after applying the anti plasmid to my syringe, jump boost was moved to the last added gene in the list. so it didnt work. i then worked for a while and made a new anti plasmid for jump boost (in the hopes that the antiplasmid i made before the update was still operating under the old version's bug... still didnt work...

are there any tests you would like me to do?

could this be because i didnt start a new game? i know some mods have issues with configs not changing properly if youve already started the game

i will have to run a test world when i get time to isolate that chance

AH HA! I think I found the cause...

Let's say that you have JUMP_BOOST and FLY genes. After making the anti-plasmid for JUMP_BOOST you draw blood, purify it, add the anti-plasmid, and purify it again.

What you have now is a syringe with JUMP_BOOST, FLY and ANTI-JUMP_BOOST. Adding the anti-plasmid doesn't remove JUMP_BOOST, it just adds the anti-gene. During injection into your self, depending on the exact order in the tag structure, the anti-JUMP gene can be processed before or after the JUMP gene. Meaning it might work for some syringes and not others.

I can fix this for 1.24, in the mean time, or if you are playing with an older version, you can get around this if you have a clean blood sample (one with no genes) and use that one to add the anti-plasmid to. As there is no JUMP gene and only an anti-JUMP gene, it will work correctly.

Fixed in 1.24
