I don’t know if this was scheduled to be fixed in this update, but bringing it up again since it just cost me a win in a recent PvP match, there are a number of MODs that are not working as intended since the Playable boss moves have been linked to them in some strange back end programming way. This is the only explanation I can think of why they would have changed, as they started to not work properly when the playable boss moves were introduced and then they got messed up further when changes were made to how the boss moves operate.
For instance this MOD:
clearly states that it should reduce the first attack by 99%, my Tylosaurus had this MOD active and had not taken any damage which means in order to kill it since it has 2030 health it would need an attack of 203,000 from my opponent so of course I don’t block. The opponent does a 4 move attack doing some ~2,100 damage and killing my Tylosaurus, here is what the screen shot looks like after this transpires:
