Hey,

the dependency "bobsplates" is set to version >= 1.2.0 but its only available in 1.1.6 so it doesn't load.

Best regards

Also having this issue, unable to play Seablock at all right now because of this

Tried to fix on Github, but I do not have write privileges

To anyone who is having this problem and wants to play before the mod is officially updated, you can manually fix it by going to C:\Users\user name\AppData\Roaming\Factorio\mods\, opening science cost tweaker, opening the info.json, and where it says "bobplates" change the version from 1.2.0 to 1.1.6 and then save the file. It will fix the issue and allow you to load it again.

Sorry about that! Working on getting it fixed. Compatibility changes for the upcoming version of Bob's mods were mistakenly included in the latest release.

A better option is to roll back to 1.2.0 . Or wait a couple of minutes until we release 1.2.2 . We've removed 1.2.1 from the mod portal.

Awesome, thanks for your quick response KiwiHawk <3
