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: 1.16.4
• MineColonies Version: 0.13.589-ALPHA
• Structurize Version: 0.13.113-ALPHA
• Related Mods and their Versions: Using Direwolf20 1.16.4 - 1.5.1 modpack

Expected behavior

Couriers should be able to zip up the ladders in the Level 3+ wooden (and other) warehouses.

Actual behavior

The couriers get stuck on the ladder, floating in mid air a bit, attempting to get up the ladder over and over. They sometimes succeed after a few attempts, but other times they will try endlessly and you need to recall them to their hut to let them have another go at it.

Here is a video: https://www.dropbox.com/s/4fqkqt788pv14kz/minecolonies-bug.mp4?dl=0

Steps to reproduce the issue

1. Build Level 3 wooden warehouse
2. Put all items in the 2nd floor, furthest from the ladders to increase chance the couriers need to climb them
3. Wait
4. You should eventually see them getting stuck as shown in the video

Notes

This is not a new bug and has been going on in my worlds for months across multiple different packs, including with only minecolonies and structurize installed standalone.

Unfortunately no, this does not fix the issue completely. I have not had a courier get completely stuck yet, so there may be an improvement, but I have had a courier get stuck for 30+ seconds before eventually making it up.

But this is also a small sample size.

Can you tell me if this fixes the problem?

@tecnobrat

Hello, I have the same exact issue as what is shown in the video with the Wooden Warehouse Level 3 currently. They'll eventually manage to go upstairs, but it could take them between a minute if not the whole day. I run the Valhelsia mod pack but updated to version 596 of the mod.

I just checked to see the change notes of the most recent updates, but I don't believe it was mentioned.

@MangoMoMochi can you try the version I posted above?

I've been playing for 3-4 hours and have been checking up on them, and it seems to be fixed, they seem to get caught up just a little bit on the right hand side ladder, but then they fix themselves within 5 seconds or so, which is a massive improvement!
