It is currently having a problem with Omega Chess, which uses aliases for some spaces. So, I'm going to have to build in some support for aliases.
I fixed the problem with Omega Chess by using aliases for the pieces and positions stored in JavaScript, and that introduced a new problem I also fixed. Since I was relying on the new $posdata variable to tell whether any spaces besides the origin and dest spaces were different from the previous move, it was no longer returning the correct results for the aliased corner spaces in Omega Chess. Luckily, I already had variables with the aliased values in the code, and I just used these to represent the current position in comparison with the previous position (which was already stored with aliases).
