Some small issues, that i have seen after upgrade:
- if i set in settings the "Unresearched penalty" to 0, the warning on hex core is still visible
- don't remember how it was previously, but now by upgrate of productivity, while Hex Core is open, the productivity does not refresh automatically (i need to reopen the Hex Core to see new productivity)
- by opening of the trade overview and switching between the trades i can see 3 loading bars for some milliseconds. Previously it was smoother.

The trade productivities get recalculated over time upon certain triggers (such as changing a mod setting), typically taking around 3-5 seconds on large saves. This is to avoid large frame stutters in other cases when trades get increased productivity like when items get ranked up. So this is why you wouldn't see the productivity change immediately while the hex core GUI is open. Previously, it was an immediate change, where all trades got iterated in a single tick (which would freeze the game on large saves).

The trade overview was causing massive frame stutters on large saves, lasting seconds at a time, because it was iterating over all trades to filter and sort them by various metrics. Those progress bars showing for a split second is definitely a little less smooth for freshly started saves, but it's significantly smoother for large saves (10k+ trades per planet, freezing for no time at all now). Is this really an issue?

I'll be sure to remove the label when the unresearched penalty is zero. Thanks!
