Pips Got Stuck in front of water

[NeoBahamut]

Hello, I recently made a Pip ranch with one domesticated arbor tree and came up with the idea of placing a small pool of two tiles of water at each side of the ranch (the "x" in the ugly representation below) in order to reduce Pips movement

Ugly representation:

The issue is that the Pips got stuck below the arbor tree (the "o" in the ugly representation above) and are uncapable of eat, move or being groomed by dupes. They eventually starve. Please help. What i am missing? Is this a known bug for pips?

Sorry for the bad english, i am still learning

It's a bug as far as I know, I got a whole crowd of dreckos stuck near my pacu tile. You might have to remove the water so they don't get stuck

Thanks for the answer, i got a Drecko breeding ranch with the same two tiles of water on each side and so far none has get stuck, perhaps it is because they have much more space to walk on, as i made an upper level where they grow scales and get groomed. While the lower part of the ranch is for eating mealwood to get glossy drecko eggs

Pips are the only critters i have found that bug so far. 

I might switch to a Pip ranch island instead. 

Again, thanks for the answer, i am new in the comunity

Old, old, old bug.

Then I asume it will not be fixed any time soon. The Klei team has any explanation about it? Perhaps it is something far too complicated to fix. Or has something to do with the game engine

My guess would be there is some race condition (i.e. timing-dependent bug) in there with really low probability. These are very hard to find. Unless you let your Pips roam free, it is not much of an issue.
