Walls: Infinite building

[Langbart]

This bug was first reported in the ​Forum by 'seeh'. He also created a ​Youtube video.

The foundation of the wall is laid and workers are working on it, but no progress is being made. I have tried unsuccessfully to find a simple rule for when a wall cannot be built. I have only succeeded in encountering the same bug, but I still do not understand when a wall cannot be built.

Searching through same Trac Tickets; the problem is the same, but the reason why a wall cannot be built is different and has already been solved.

• #1406 Units run across foundations that cannot be built.
• #1450 walls are not built
• #2132 Units do not close a wall correctly.
• #2906 Some walls are never finished or take an unusually long time (duplicate of #2906)
• #5118 Walls are not built when the foundations of the wall towers overlap.

I will attach 2 files:

• seeh_replay.zip (the problem is seen at about the 7 hour mark).
• paladin_replay.zip (the problem can be seen at about the 35 minute mark)

(I'm just creating the ticket so the bug will not be forgotten.)
