I believe this is because you are using the wrong version of Computronics. You need a version of Compu for the beta version of railcraft. There is a message with a link to it in the Railcraft discord in the #general channel

Actually never mind that, it's better to just link it here:

https://towerofawesome.org/files/Computronics-1.12.2-1.6.6.192-rc-beta-5.jar

Thank you :)
Would be nice to have it over https://wiki.vexatos.com/wiki:computronics as well if you know who to contact about that!

And nevertheless the warnings in chat from the beta version of Railcraft somewhat discouraged me enough to wait for a more stable release.

@Forecaster Thanks for the info! I can't find it unfortunately.

Hm, the link in the message is broken anyway, and it's not the latest version, I have a more recent one.

If you ping me in the Railcraft discord I'll send you the latest one I have which should solve the issue

That would be Vexatos, but he probably wont want to post a beta version there

Nowadays Computronics-1.12.2-1.6.6.192-rc-beta-5.jar doesn't work with Railcraft 12.1.0-beta-8, but Computronics-1.12.2-1.6.7-railcraft-beta-8.jar does. I've found this version in general of official Railcraft's discord guild, thanks to this message.

P.S. I'm posting this message for those who struggle with this incompatibility and found this issue as I did. You can download compatible version from the guild or try to find it on the net.

@Lukramancer It was built for Tekkit 2 by poking Vexatos enough, I've also recently asked for the source to be published (https://github.com/Vexatos/Computronics/tree/1.12-railcraft-beta-8) although building from source takes a bit of effort.
