AFAIK most of those issues are due to event ordering issues (including the various load/validate notifications on the TEs) or even missing events.
We don't always see a reliable load -> unload -> load -> unload order, but glitches such as load -> load -> unload -> unload, which makes it very difficult to reliably maintain a representation of the energy grid. Likewise, the wrong world warning in your logs indicate some sort of missing or misplaced event.
We can only further improve our workarounds, but until we're done with porting to modern MC further work in this area will have to wait.
