[2.1.15] Crash opening production or electricity statistics (FlowDataFrame check fails)

[Boraborawayhay]

Whenever I open the electric network or production statistics (by clicking on a power pole or pressing 'p' respectively) on my Space Age world, the game crashes. This occurs on both Nauvis and Vulcanus, and both singleplayer and multiplayer. The issue is new and didn't happen around an hour ago on the same world, where I could look at either without issue (and the game wasn't quitted and reloaded in between then and the first crash). The issue only happened after the first landing back on Nauvis from Vulcanus, in case that's relevant.

My friend did not have any crash issues, either on multiplayer with me or them hosting, or on singleplayer (apart from the fact that when I crash as the host, they get disconnected). However, when they host this world and I join, I still crash when opening either UI but they do not.

Thanks for the report. This is now fixed for the next release.
