I've seen that compatibility was added to allow lanterns on fence posts, but it would be nice to also impart that ability on posts made via the Forge Microblocks API, so that you can take advantage of different block types from other mods.

ATLauncher: Resonant Rise 3 (v3.2.4.3)
MC: 1.7.10
Forge: 10.13.2.1291

FMP issue, was fixed.

I'm using PROJECTRED-1.7.10-4.5.15.75 in the Resonant Rise 3 pack and it doesn't allow me to post lamps on microblocks. What release version was this fixed in?

One of the recent few versions of FMP, i believe.

Noted, thank you.
