Describe your problem, including steps to reproduce it

I'm getting lots of lag with a small world, there are only two main mods in the pack, PneumaticCraft: Repressurized and Mystical Agriculture. It often helps to create a server with the same mods and play against this server.

When creating a server with the same mods it is crashing, single player doesn't crash. The server is crashing because the tick takes more than 60 seconds.

Any other comments?

I've built the base near world spawn so the chunks will be loaded. However, I don't think this is the cause. On problem with the server version is that drones don't go back to the charging station to recharge.

This looks like pathfinding gettting itself tied up in a knot and infinitely looping somewhere and I actually fixed something sort of related in 1.16 not long ago. I didn't backport the fix at the time but I'll do that now since it could help here.

Give build 62 from https://jenkins.k-4u.nl/job/PneumaticCraft-Repressurized-1.15/ a go, and see if it helps any. Other than a fix for drones not navigating to the space above "tall" blocks like fences & walls, this also reduces a max-path-length constant which was incorrectly far too large (i.e. if the drone can't find a path, it'll give up after 1000 blocks now instead of about 2 billion...).

Same problem I'm afraid. https://pastebin.com/QdzAHs4r
.62 crashed during the startup, .60 didn't do this. Currently, I'm testing .61 on the server.
Thanks for your help.

Oops, used a client-only method (which isn't client-only in 1.16). Build 63 will be ready in a sec, should fix that.

I think this change has made a significant difference, both sp and mp are much smoother.

All the drone should be able to find a charging station within 50-80 blocks, which is where I would guess that they would be going.

Many thanks.
