Hello there,
Taned here.

I have recently updated my minecraft.
When I go on to my world while using any texturepack (they are all updated)
All of the potion's glass is not see-able.
I'm not sure if this is only my minecraft or others have been experiencing it too.
If it's just mine, please help me to fix this problem.
If there are others who have it too, I'm not gonna worry about it.

Thanks.
