I am running Minecolonies 0.13.386 and Structurize 0.13.92.
On minecraft 1.16.3
Also running Voxelmap 1.10.11
No other mods

I get intense lag spikes after I place down the fortress hospital hut block. I have tried to move the block to different locations, and have placed other hut blocks to try to recreate the issue, but it is specific to the hospital hut block

Had someone on discord with this same problem - couldn't remember where I had seen it reported before! They were on mcol .547 and structurize .104 - fortress hospital block as well, completely lagged them out and chewed up their memory. They gave the game 1 gig more memory and it didn't stop, then gave it another 1 gig before it stopped (they had assigned 4 to the game, ended up with 6 to stop the hospital block lag)

Please fill out the template or at least provide the latest.log

a) template
b) Does it happen with other hut styles too?

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: 1.16.3
MineColonies Version: 0.13.386 Alpha
Structurize Version: 0.13.92 Alpha
Related Mods and their Versions: None

Expected behavior:
After I place down the Hospital hut block, I should not see a consistent FPS drop to 0 every 3 or 4 seconds.

Actual behavior:
After I place down a fortress hospital hut block, I receive lag spikes every 3 or 4 seconds.

Steps to reproduce the issue:
Place a fortress type hospital hut block and experience lag spikes.

Notes:
I tried restarting MC, and my computer. I also placed down other hut blocks to try to recreate the issue, but it seems to be specific to the hospital hut block.

I will try with a different type (such as acacia hospital). And if you need any logs as well

I looked into this. I think this is because the hospital block has a relative "complex" model which on weaker gpus/cpus is causes some issues. However, I tested this exhaustively and it should not be responsible for those extremely low drops.
