Minecolonies 1.15.2
Version: 1.15.2-0.11.949 ALPHA

Expected behavior

It would be nice if the entity flashing would stop so I don't have to always run a shader.

Actual behaviour

For the past 2-3 weeks I have been experiencing a bizarre flashing that I can only describe as appearing to be bits of distorted texture from the blueprint schematics (those when you view the template before you place a structure). This problem only occurs within the colony limits and occurs in any world with the colony. I have tried deleting and reinstalling the game version folder ( I have separate folders for every version, each with entirely different saves and a fresh install of the game version)

I tested if it was caused by other mods such as JEI, timber, useful backpacks, and optifine, but it all seems to be coming from minecolonies. I will continue testing out different solutions and update if I find one.
I am not able to include a video in this report but I am more than willing to send one via email if necessary.

Steps to reproduce the problem

My colony has townhall level 3, the entire colony in medieval spruce alternative theme
2 builders at level 3
A warehouse at level 2
2 deliverymen at levels 2 and 3
2 level 3 citizen huts, 4 level 2 citizen huts, and 1 level 1 citizen huts
1 Blacksmith level 1
1 smelter level 1
1 university level 3
1 mine level 3
1 restaurant level 1
1 shepherd level 3
1 farm level 3
1 cowboy level 2
1 lumberjack level 3
2 guard towers, level 2 and 3
1 pig farm level 2

I don't exactly know how to reproduce it but perhaps it has come with one of the buildings. It wasn't an issue when first building the colony.

There's absolutely nothing we can do about this issue as of current. it's Optifine's issue and fault
