No metal excess until AI was raided, so seems fine to me.
But were there any changes to metal/energy pull/income calculations in ZK?
I'll compare the values that AI calculates with those that economy bar displays...

"Sharing & Overdrive" is somehow strange, and AI doesn't count it, because it's only side effect of having more energy than AI needs.

I'll exclude enregy tasks from ms_pull rule (currently only mex and pylons are excluded) and will make limit of active tasks for energy larger.
Energy may be bounded by ms_pull value and it was re-configured few times.

Not sure which change is necessary to fix stalling, but AI seems to stall much less with both of those changes on current map (unless it's in the process of building 1st fusion).

what is the reasoning behind pylons being excluded from ms_pull?
In the middle of the game when there are many tasks along battle fronts (usually defences) AI grids very slowly: delays pylons if not enough units were built (ms_pull rule).
I guess same is happening with energy in current stable. But if it's stalling - let it build energy at high priority and it will have a chance to build more units. I didn't notice energy overproduction with described change, but more tests must be made.

WRT disregard ms_pull only until some criteria: need to test new changes without limitation first, they looked harmless in my very few tests, so i against overcomplications atm.

well, true. But apparantly - can't exclude from ms_pull mex without energy and energy without mex, economy structures should go as a group.
To enable ms_pull for everything change mex_max to 0.99: it should mex whole map, except maybe last spot under rare conditions, and use ms_pull for everything.

I'll consider criteria to enable/disable ms_pull later after some tests.

Ok, next version (0.9.20, not 0.9.19) will have something like ignore ms_pull for energy only if stalling. For metal leaking: it already works almost like IK described, except that limitation is ignored but metal value is still counted.
