Sorry Caliber, I certainly didn't mean the trainer options were not very useful, or hard to hack. Thanks for your work !
I just meant that for most of my games, it is enough for me to hack a few surrounding resources and add a few research points. For any hardcore mode playthrough, I will use the trainer more.
I have found a few issues with the instant-build and auto repair options, though.
The instant-build option does not register the building as finished, which does not unlock research or achievements, but also disables the villager's auto-repair orders for this building, and any other auto-work feature of the building.
The worst is for stables : villagers will not auto-feed animals in a insta-build stable !
You have to keep giving manual orders, for repairs, feeding, or any other activity.
The auto-repair option can cause strange behavior when you have some buildings, like walls, in construction.
When I activate the option, any wall not yet built will have full health, but still be unbuilt. So it never actually gets built at all.
Apart from that, the only other potential issue I encountered is that the full health option works for every human and animal on the map.
I can live with these issues, and work around them to use the trainer.
But maybe a warning would be useful for others, or even a fix if one can be found.
Thanks !
