Since the last release I have come across a bunch of small problems and some larger ones. The biggest problem is that LOM did not support multiple number formats so if you live in a country which uses the comma as a decimal separator then the program could easily crash or fail to compile the scenery. I realized that the problem was endemic in the code.
I have known for some time that my original design was not flexible enough especially in Scenery Maker so I have bitten the bullet and re-designed all the underlying code including a new user interface. It is mostly working now but I am still tinkering.
