I know that Soviet Flans mod might not be the real Flans mod so please tell me if I have no right to submit Soviet Flans mod bugs and problems **Describe the bug** So,I was testing out the Soviet Flans mod,trying to enable some nice russian cars.But when I try spawning such,they become invisible.Simple Parts Pack is installed.Watch the screenshot.

Screenshots

Mod list:

I recommend you try the latest version of the mod https://github.com/FlansMods/FlansMod/releases since your version is very outdated.

I think the invisibility issue is most likely due to the content pack or other mods.
I recommend trying without other mods and then if the issue persists, report the issue to the content pack creator.
