Weird behavior: Daytime changes on either (any?) surface seems to modify the solar panel production for a cross-surface network.

Steps to reproduce:
1. two surfaces, one small-electric-pole on each for simplicity
2. connect: 3. place solar panels on one surface
4. accumulators on other
5. Change daytime on either surface e.g.: Result:
If you are on surface 2:
Changing surface 1, the solar panels stop producing power on the entity. (switched back to surface with editor) The network is still producing power.
Changing surface 2, the network shows 0 solar power even though the solar panels aren't there, and the panels on surface 1 still show power.

If you are on surface 1:
Same as above, so maybe there's a build-order dependence to the behavior?

Save prepared:

Thanks for the report. Unfortunately that's a side effect of using this feature that isn't likely to ever change.

This issue will be fixed in 1.2

Is this a clue for what will come in the expansion?

I'm happy for improved surface connection support. It's such a cool feature and the mods it has brought are some of the coolest ones ever
Thanks anyways for always making Factorio better and better! <3

No, i was simply doing code cleanup because an ElectricNetwork had a surfaceIndex and i wanted to get rid of this. There were exactly 3 places that were using the surfaceIndex and all 3 of them were broken: solar panels were using that surfaceIndex to obtain a daytime, lamps were using that surfaceIndex to also obtain daytime, and drawing of electric network lines in chart view was using this to filter which networks to draw.

Ok. Fixes for all 3 issues (solar panels, lamps, electric wires on chart) were backported and will be available in 1.1.79.
