Minecolonies version

Minecolonies: 0.8.6934
MC: 1.12.2
forge: 2601

Expected behavior

The Builder should find most direct path to destination, and should choose a single block as destination, in order to build the current project

Actual behaviour

The Builder wanders around aimlessly, or gets close to current project, but wanders in the area, sometimes path finding through the area required to actually build, but mostly getting stuck in corners, or on the roof of buildings. (from a non-coders perspective, it seems that the builder tries to find the highest point he/she can along the path, and then climbs, often getting stuck on a roof or tree)

Steps to reproduce the problem

1. Install proposed versions of applicable mods.
2. Get enough of a colony to have the builder able to build things
   *I dont know if level, or type/amounts of buildings matter, but I currently have:

• Town Hall lvl3
• Builder lvl3
• Miner lvl3
• Sawmill lvl3
• Deliveryman lvl1
• Warehouse lvl1
• Currently attempting to upgrade deliveryman to lvl2

3. assign the builder to upgrade a building.

Extra Notes:

My world was recently corrupted (unrelated to your mod), so I am in creative using the builder's tool to place the colony. I select the lvl1 form of the building and select the left blue icon at the bottom of the screen to have it placed automatically. I then remove the "placeholder blocks" and replace them with grass (via creative mode) and choose to upgrade the building.

Attached is a screenshot of the builder stuck on a tree with the pathfinding display on. but a similar situation happened with other buildings of other levels. but all buildings placed so far have used the same method as outlined above, and most have had at least a small amount of builder related issues.
