Yes, but not working with Uplay...
Strange thing is i started this sim few weeks back, with a megamod founded on french forum (mille sabords) called "Haddock megamod" (maybe you know it?), and the hydrophone station IS working using this megamod!!
(that's why i never noticed this stock bug before BTW)
So then, i decided to make my own mods soup using latest versions of mods here on Subsim...because Haddock megamod seems to use only old ones...
I realise now that was a bad idea (for my hydro post anyway)
What i'm going to try now, is to change only few old mods from Haddock toward new ones, and see what happens. One by one obviously, to detect weird things, mainly watching out the hydro station!
Finger crossed
