Okay I've been palying RCT3 for about a month now. I created an awesome and perfectly synced dueler in sandbox mode. I have used the file, saved it (obviously when I turn off my computer), and turned it back on to edit it. I have done this about 5 times. Then today, when I try to load the track (in the same manner I ALWAYS have), I get a message that says something like "Could not load track, the following (non-installed) add-on packs are missing:". It doesn't even list the add-on packs (which I know exist, but I know this track MUST function fine without the expansion packs since I have used it without the expansion packs before.
Also, my system specs are way above the minimum, and my drivers and game version are updated to the latest versions. I also have installed no additional objects or files to the game since I installed it.
So ... what gives? I'm guessing that I can't be the only one that is or has experienced this glitch.
Can someone please shed some light on this? Because I'm surely not buying the expansion packs for a base product that functions poorely in the first place.
