Issue Description:

When painting facades with forestry wood, they render with a large ! in-world.

What happens:

After the update Forestry 4, all my balsa wood facades were just a white box with a large ! on them. They render just fine in the inventory.

What you expected to happen:

The facades look like the block they were painted with

Steps to reproduce:

1. Grab Forestry 4
2. Paint a facade with one of its wood planks.
3. Be disappointed by the look of these

Affected Versions

• EnderIO: 1.7.10-2.3.0.424_beta
• EnderCore: 1.7.10-0.2.0.34_beta
• Minecraft: 1.7.10
• Forge: 10.13.4.1566

Your most recent log file where the issue was present:

don't think this will show up in log, but can provide one if requested

That means that Forestry rejects to provide the block's texture when Ender IO asks for it. Nothing we can do here.

PS: The other reason could be that the block the facades were painted with in the past doesn't exist anymore. Have you tried painting them again?
