Hi Illiander42,
0.17 is landing at the worst possible time for me. If however you upgrade before me -- I believe you were planning to deprecate anyway -- bad things will possibly happen to my mod. A lot of state is stored in the mod save game, new games started with my original mod won't properly be compatible with your variant and vice versa. So it'll seriously split the player base, as they will only see yours, and probably lead to bug reports if players try to switch.
It's only about two weeks before I can give it my full attention, and we've waited this long for 0.17. I am sure the update has plenty to keep everyone occupied for a bit anyway! My plans for mod development got really messed up by the 0.17 delays, but I have plenty of stuff planned. So I'd really appreciate being given a couple of weeks to get to this and do a thorough job.
