The mods referred to in the title add thirst and temperature systems respectively, which are very incompatible with the Origins mod atm. For example, enderians and blazeborns get damaged by drinking water from a water bottle, merlins constantly get cold because they are always underwater and blazeborns have a hard time in the nether because it's always hot. This is somewhat easy to deal with in singleplayer since you can mess with those mods' configurations, but it's really inconvenient from a multiplayer standpoint. It would be really cool to see an integration that would allow for players to use these three mods without these game-breaking issues. Maybe some condition that would disable the thirst system if the player chooses water-incompatible origins or create body temperature limits for players who choose blazeborn or merlin origins? I suggest installing these three mods together and testing the different features to see how incompatible some origins are. Thanks in advance :)
