I had a chance to look at the current state of things and found out part of why it got left for a bit... took me couple of hours (that I only sort of had) to sort things out but apparently I was half way through shifting a bunch of things into a new category ("Heavy Plant") because the "Town" category (which is really "Town", "City" and non-descript mixed together) was getting too big, especially with some of the models I had planned for the future (which I have now found) but have no time for.
I also added three new (lower-medium sized) sets that had been queued but got lost in the mess of uncommitted changes and found a fourth that will need a bit of work before it can be added but is close (but also apparently incomplete, so maybe it will have o stay in limbo until that is also sorted out!!)
I don't know when I might have time to do more but now that the mess is sorted I feel more confident abut seeing if I can knock one or two more out (assuming RL doesn't whack me over the head again! ;)
Hope you enjoy the sets and thank you for the motivation to look at this again! :) - I tried out a couple today and the bug bit me again... just like it has been biting me my whole life! :D
