space-exploration 0.7.35

Thanks for the report. I've been pretty busy but I'll try to get to it ... there are at least two other bugs, maybe three, to look at anyway. * Router I/O nodes need to be selectable, but they have a lower selection index than ore (at least in py), so you can't click them if they're on an ore patch. * The subcomponent of router I/O nodes that receives power isn't properly rotated when the router is constructed, so in some cases the I/O node can receive power from poles when it looks like it shouldn't or vice/versa. * IIRC routers are slightly asymmetrical (for graphics reasons) which makes blueprints not always work when rotated, because wires don't reach. It would be good to resolve this without breaking the graphics.

I couldn't reproduce this bug with space-exploration 0.7.36 and my local development version of routers (should be the same as 0.2.7 in the important ways though). Is there another mod adding turbo belts?

This two maybe Space Exploration Integration: Turbo Belts with Turbo Belt

When i turn the two mods off i can load the game, but there is a new error when placing a router

I think its linked to Quality (SE-compatible fork)
Its appears only when placing Epic and Legendary, the first the qualities are placeable

This was a Legendary express router
Error while running event router::on_built_entity (ID 6)
Unknown entity name: router-component-input-stack9-express-loader

OK, give it a try on 0.2.8. I didn't test with that quality mod but I reworked the quality handling in a way that's simpler and hopefully more robust.
