Maybe i'm fool, sad_wojak_face.jpg trying this way to revive my heartling..
However, i realize that without ~2-3 back swimming teleportations and last back teleportation, when i was, imho, already on the shore, BTP rolled my heartling back to the bottom, i was like NO WAY WHY YOU TELEPORT ME BACK?!!
You can only believe my word, but there's bug and this is a fact. my const was about 24~ and stamina maybe 50-80%(just calculate, i dont remember)
sad thing.
You can do nothing or you can fix this bug, i hope you revive my heartlingi dont believe like it would be best gift to me. but please, i hope something will be changed.
