Forge no longer uses coremods. So there is no chance of it working "as is" since it requires the CoFHCore . (Also i bet there are other changes that would also make it incompatible)
Erm... Coremods are still a thing, they just have a single directory instead of two seperate ones.
But yeah. Minecraft changes its obfuscation almost every update, so when MCP changes the names around, all of the things that referenced those break. (Or at least that's my very basic understanding of roughly how it works. Modders, feel free to correct me.) On top of some Forge stuff, and changes in Forge from update to update.
I am getting this weird issue. I have a bunch of Forestry machines and I have liquid coming out of them and into tesseracts with liquiducts. When I logged off and back onto my server, I realized the liquiducts filled with water, preventing whatever processes were supposed to happen (I have it chunkloaded). I am wondering if this is a Thermal Expansion bug or a Forestry bug.
Water bees and any bee with the "Water" effect fill tanks with water. Put their apiary farther away or as recommended use an MFR liquid router to a void pipe for water.
