Path calculations broken

[TradeMark]

See in below image:


I've noticed long time ago that on flat maps it cant find the path sometimes, even when the destination is only 500pixels away from it.

Edit: managed to make it crash when i clicked on another location with con vehicles:

After randomizing the heightmap it seems to work like it should:



Edit: tested again with less random, only 1 height differences on the surface, and it works too:



I noticed i tested only with arm units, but after testing with core units, it works as well as with arm units.

[zerver]

Yeah, i agree something is wrong. It has become much more common for units to refuse to move when you give them an order.

[Tobi]

Does there exist a released map on which this is reproducible?

[TradeMark]

i think this should be:
http://mapinfo.adune.nl/?map=Speed_Ball ... NoMetal_V3

not sure tho, but its exactly the same heightmap i used in testing.

--

i think this might have something to do with this:
http://springrts.com/phpbb/viewtopic.php?f=11&t=20967

nevertheless, my maps arent the only maps where ive seen this behaviour, for example on Tabula flat places you can encounter this bug too.

[Tobi]

Can't reproduce it. (yet)

[TradeMark]

did you try isle coordinates 0x0, 3x3 and 1x1 ?

would it help if i send the replay where i tested it? (if it even recorded it...)
