No i have XP 3000+ ( but no stucked units on land, only water)

The other water issue has been exautively discussed and entirely ignored by anyone who can fix it.

Well looking at code I guess it should be possible to specify that subs are "flat" that means they would be just like aircrafts - being able to stack on top of each other and travel below ships / above underwater structures.

Corresponding tag for modders is called "blocking".

However this property is set to true for all units in unit.cpp contructor:

//All units are set as ground-blocking.
blocking = true;

I tested it by setting this to false for submarines and it worked nicely

Maybe it is related? jcnossen reported to not experience stucks and, as far as i remember, he has a fast PC.

ship pathfinding sucks indeed, I should really read posts better next time...

Replace submarine pathfinding with aircraft style.

Aircrafts in spring have pathfinding? I thought they just sortof randomly flew around until the target order you assigned ended up under them. It often seems that way anyways

Well good luck with that.. you would have to write taairmovetype equivalent adapted for subs and change stuff in other (hard to find) places as well .. Tbh whoever wrote this initiailly should fix it..

Setting unit's as non-blocking is not a solution, because spring detects collision anyway and if you happen to be in same place as underwater metal contructor or port, your unit will get shifted or explode..

Carefully reading all posts posted in these forums wears you down really quick. I've been there.

your solution doesn't address that fact that BOATS can't travel over submerged buildings!

Yeah, you are right - non-blocking unit doesn't block only with another non-blocking unit. It's not a solution .. proper movement model for subs and ships is..

But for the starters I think it would be wonder full to just fix ship above sea-floor building movement problem..
