Addons Section Just As "Out Of Date" as Buildcraft Utilities

[BraveCaperCat2]

There is currently an official forked version of Additional BuildCraft Objects available Here - Please update the Addons Section.
Additional pipes is now out on Curseforge and has a alpha version for 1.12,2 Here - Glass Pipes is now out on Curseforge Here, although they don't have 1.12.2 out yet, Buildcraft Additions is out on Curseforge and has a 1.7.10 release Here, although Buildcraft Utilities is nowhere to be seen (on Curseforge)

Conclusion: So yeah, you need to update the addons section of the mod's website
