Overlapping ores. One cannot be mined

[Carlytuur]

I'm doing a full pymod game, where I have two ore patches that slightly overlap, being Chromium and Titanium ore. Both need respectivily SynGas and Acetylene as addition. I noticed that when the mining drill is over a combined patch (Chromium and Titanium as expected resources), with SynGas addition to the the mining drill, it starts mining the chromium ore, but when I use the Acetylene as addition, it does nothing. If I place the drill over a patch with just Titanium as expected resource, it works fine. Any ideas?

Just to clean up the dividing line

Easiest solution is to get what you can and ignore the rest. There are other patches.

Less easy solution: when a miner starts a drill cycle, it chooses an ore tile at random from its area and produces that. If you have a patch of A with a little B, the miner will drill A until it rolls a B tile and then halt (or vice versa). So place a miner such that only one corner of the drill area covers a single kind of ore and it'll run at full speed until the tiles are exhausted. Then move it a little bit further in, etc.

I wonder if these would help ?
