Prerequisites

• I am running the latest alpha version of MineColonies and Structurize for my Minecraft version.
• I checked the MineColonies/Structurize wiki and made sure my issue is not covered there.
• I made sure that this issue is not a duplicate of any existing issue.

Context

• Minecraft Version: 1.16.5
• MineColonies Version: 0.14.356-ALPHA-universal
• Structurize Version: 0.13.210-ALPHA-universal
• Related Mods and their Versions: Adventure Server 3.8

Expected behavior

Properly utilize the rails to get from point A to point B at really long distance.

Actual behavior

So, one of the things I noticed with rails. IF the civs, (Notably builders.) that have a distance really far away. 300-400+ they will repeatedly hop onto the rails, then hop off of the rails, take a few steps, hop back onto rails and repeat. I've have seen this happen at least 2 different builds.

The first time, the builder was working on the Decoration / playerhousing / Asian. The builder worked like normal, until they were working on the back / upper levels of the decoration. At which point I noticed their behavior. I accidentally killed the builder by punching them, causing a Mahki to spawn and kill them. When the new civ was hired to replace the builder, the 2nd new builder had the exact same behavior.

Steps to reproduce the issue

Have a builder and a worksite a far distance away.
Have rails set up in between two points. A distance between the end of a rail and the build site may be required.

Notes

I have witnessed this behavior twice. Death of builder did not change behavior. I did have a mix of powered and regular rails. There was a few chunk distance between the end of the rails and destination.

At the times, I did not have roads set up (The second time was in the process of placing the Caldonian roads. Starting up in the top left.); however, inside my moat were rings of "grass paths" placed as a part of "Asian planning, wall" Which may have effected pathing calculations.
