Yo, Mojang 1.0.5.13 is getting alot of bugs, but I want to get into one that started in 0.16.0 and was never found. With some texture creators 2 spawn eggs and new blocks get texture bugs like the Spawn Shell Lurker, the Spawn Old Guardian, and my least favoroute block, Gravel. Also sense 1.0 i don't know if this is a bug or a feature, but on Windows 10 you can pickblock a lit end portal and it has the texture of the dirt block that says "Update."
THE PORTAL BUG WAS FIXED!
