Overview: A couple of updates back, I made a thread on how the BOTI Paintings would glitch in a way where if you got close to one, the image inside it vanishes. This bug is still around, even displaying different behavior, which also extends to the SOTO doors.
Description/what is the problem exactly? Whenever you add an image to a BOTI painting, and if there's anything directly behind the painting, like say if you put it on your house's wall, what's meant to be in the painting is completely invisible, leaving only the TARDIS dimension void/background. As well as this, the SOTO effect of any TARDIS doors also produces the same bug. I could be wrong, but I believe the SOTO doors are only affected if you at any point place down a BOTI Painting; seeing as the SOTO was fine prior to making these tests.
Did you use Optifine or any additional mods alongside the Dalek Mod? As usual, when testing to see how the bug works, I removed all other additional mods, including Optifine, and created a new world before testing.
Crash Report: N/A (it doesn't cause the game to crash)
Screenshots/videos: Below are two short videos demonstrating the bug in action. Hopefully, they are sufficient.
