I'm roughly new to anything involving mods but I used to use BOP in 1.12 and I updated to 1.16 and found this mod to heal my soul from missing the hot springs, but I tried placing the water down and nothing happened, I reinstalled all my mods one by one, and it seems that whenever I have roughly enough items in my mods folder it does not like to cooperate. if I made a dumb mistake, I'm sorry but please help me out, I adore this mod and would love to use it.

Thanks for letting me know! This appears to be an issue with REI, since it also seems to happen with other mods that add fluid buckets. I've made a bug report on REI's github.

Thank you very much, this may be a issue on my part but it also doesnt allow lilly pads from other mods such as terra incognita, no worries about it though.
