In the latest update for the Dalek Mod as I post this, which is Update 59.1, whenever you create a BOTI painting with a Stasis Cube, the image inside the painting completely vanishes when you get close to the painting; only reappearing when you look at a certain angle/direction. Below are screenshots that show examples of this bug. This has happened in every world I make or load, and each painting I try it on is new.

Any other mods you might be using? Optifine with fastrender? CMDcam?

 Nope, I can assure you this was later tested without any other mods

How do you make a BOTI Painting?

https://www.youtube.com/watch?v=U1t58EInWpA&ab_channel=SWDTeam at timestamp 11:37 you can see how he uses a Stasis Cube to set two positions, run a certain command, and then you click a blank BOTI painting with the cube to create one.

 Tutorial coming soon… ;)

 I should probably point out I'm still experiencing this bug in Update 60.
