Hi, using v1.2.5 of DoubleSlabs with minecraft 1.14.4.
Whenever a double-slab is placed (In this case, a double stone bricks slab), the texture works normally, however, upon unloading and loading the chunks (Serverside, reloading the chunks clientside doesn't cause it), the texture changes into a missing texture.

Update: removed my resource packs, and the texture changed to this.

Really strange.
Cycles every time i change resourcepacks, probably just minecraft trying to fill in the gap lol

Update 2: Found this error clientside

I believe this is a duplicate of #15 and may be due to having Immersive Portals installed
