1.7.10 version 9.7.0.0 My steel tanks are not rendering as a multiblock structure upon login and i have to break a block and replace it to render correctly, If a picture of mod list or a screen shot of the tanks are needed please let me know.

Thank you =)

This is usually caused by Cauldron.

i do not have Cauldron installed. These are the Mods I have installed. Here is my mods list: http://pastebin.com/sA7wne3a

It is an updated version of Bevo's Tech Pack

Can confirm, Cauldron is not installed.

Lately I've noticed this is happening more on server restart and login appears to be fine now. Have since updated quite a few mods, so I wouldn't be able to identify a culprit if any.

EDIT: Also, this actually may be related to EnderIO. It's been known for a while now that they are having a rendering issue with mostly conduits among a few others. I even recorded a render issue. A link to my post here: SleepyTrousers/EnderIO-1.5-1.12#2910

I'm encountering this issue as well, but Ender IO is not installed on my modpack, and it's using Forge, not Cauldron. In the case of my modpack, the reported multiblock being affected is the blast furnace.

Possibly fixed by 1fa265f
