Description

Double doors only works when opened by hand or button.
Redstone signal and pressure plates only opens one door.
I tried using only Forge, Optifine and Double Doors/Collective, but the problem persists.

Update
Regarding pressure plates: It seems that only 2 of the different pressure plates are not working: Light Weighted and Heavy Weighted. The other pressure plates (i.e. oak) do work as intended.

Screenshots

Button used, double door is working:

Using pressure plate, double door is not working:

Trapdoor using pressure plate, not working:

Redstone not working:

Same for trapdoors:

Thanks for giving the mod a try and opening the issue! I've fixed weighted plates not triggering double doors in version 3.3. I've not made a redstone signal a trigger on purpose, as it can mess with redstone contraptions. It's definitely possible to make a double door open with redstone, you'll just need to do it the vanilla way.
