I’ll try to install Time Control Fork and see if there is an incompatibility, but it’s a little unclear which mod actually caused the problem. For now, I’ll assume it’s mine :)

I've had a look, and it's a bug in Time Control Fork. It's caused by Logistics Insights changing a global mod setting during startup, and Time Control Fork assumes that the settings being changed are per-player ones. It's a simple fix, but it's not one I can make :) Will you report it to the mod author?

Here is a workaround you can use for now: Uninstall Time Control Fork, then load your save with the new version of Logistics Insights set up. Save that game, and you can now re-add TCF. The problem is caused by code that upgrades the Logistics Insights mod to 0.10.6, so once that's done it should work again.
