A rework of the interior flooding mod called OopsAllFlooded since it broke with update v60, and I don't think it is going to be updated anymore but I absolutely loved the concept of the interior flooding with flooded weather and combined with the Oxygen mod it created a great atmosphere. There were only a few things I disliked about OopsAllFlooded which were the fact that it didn't affect enemies at all and it was generally just unfun to walk around in the water because of the stamina drain you get from simply just touching a water source.
My idea was to either make certain enemies avoid water altogether or slow them down as well, for the stamina problem, simply making the player a bit faster and not cause stamina drainage by just walking.
It would also be cool to add the (V60 spoilers) ||water leaking effect from inside the caves in the new interior|| to flooded interiors so it would feel more dynamic.
Other than that OopsAllFlooded also wasn't very configurable which was a shame but i really hope someone remakes this because I found the mod to be very underrated :D
