I'm currently playing Enigmatica 2 (MC 1.12.2) through the Twitch app, which has AS (v.1.10.3) installed. When I right click on the telescope, the GUI shows up, but there are never any stars, just black rectangles. Even when rotating the telescope via the arrows, still no stars. I am doing this at night. I have disabled all resource packs and still nothing.

Ok, so, I just moved the telescope out 1 block (away from the cobblestone and tank with liquid starlight) and now it works perfectly

Screenshots of telescope location with regsrd to nearby terrain?
