[Issue] Pawns walk over storages

[VasVadum]

Pawns keep walking through skips when getting materials from the other side or just pretending skips don't exist when path finding. This causes extreme slowdowns, especially in my stone cutting room where the pawn will literally walk over 3 skips in a row each with 12 stone chunks just to get to the stone cutting table, then back over those 3 again to get to the stone chunk on the opposite side, causing him to walk at like 5% the normal speed when he could have gone around the skips 95% faster. Pawns need to path find around skips, perhaps make all storages impossible to go through so they can no longer walk through them anymore.

There's an example of my setup, where pawns can get to everything without walking through any of them. However they choose to walk through the slowest part of the skips every time.

Here's an example of bad pawn behavior. The pawn specifically walks over the slowest possible path with these storages. It makes no sense at all.

Bitch at Ludeon... Pathfinding is broken in A17

TynanSylvester Lead Developer It's exploiting a precalculated large-scale region grid... inaccurately.

TynanSylvester Lead Developer It's broken in A17 due to some optimizations, we've improved it for next alpha.
