Hi mezz,

Hope you're doing okay <3

I just recently re-downloaded started created another modpack with ATM9 as the base.
I updated most mods and the forge loader to the latest then tried launching.
First launch and I got the error previously described.

Thank you for your time, work and patience with me.

As always, I hope you have a nice day. Please take care :)

Thanks for the report!
Please try updating your pack (ATM 9) to the latest version, everything should work fine.

Hi mezz,

Can confirm that staying on versions of the mods provided by the latest version of the ATM9 modpack works.

Thank you for your time :)
And keep up the great work <3 Take care (*-*)

Closing issue.

Thanks for confirming the fix!
