The recent change from uint to int is causing mods to have incompatibility problems. Mods that rely upon using the internal functions of the dynamic arrays such as Size() are unable to convert from one to the other. It just says "Cannot convert from UInt to SInt" or something along those lines.
Odd, I'm no longer capable of replicating the issue anymore. Perhaps Ricardo, during his ventures, ended up fixing it. Should it crop up again I'll re-open this.
