That would be my UIs mod. You can find it in the SH5 mods workshop :up: I just released v6.4.0 of it yesterday :DL

i think its set so you can never go lower then the highest point within a given range so if you are near a rising formation it can look like you almost get there but it sounds like what is needed is to use magic to raise the visual image to meet the sub and let the game go ahead and still think you are off of the bottom as it seams determined to mandate.

yet you bottom out when beaching the sub shallow so seafloor must be controlled seperate from whats considered to be land

This is the most irritating bug as far as i,m concerned. I once hit the "bottum" while there was at least 30 to 40 meter water underneath me! Such an immersion killer and so obserd!
