I literally made this account because of this constant spam of script errors via the Register portion of the mod. I've noticed (since I made this world earlier today) that every few seconds of game play I'll get tens of script errors for so many different sims. Well after a bit I decided it was annoying and tried to find the source myself, only to find that every single error ties to a proprietor, and when searching for them I found a mess of them (at least 30) on one lot. I've annilated two so far and will continue to do so just to try removing this crowd, but I'm not sure what's causing this problem or more exactly started it in the first place.

Here's the latest script error I found in my documents folder, as well as a screenshot of what I found in front of the 'Port-A-Party Mini Warehouse' in Bridgeport. (Edit: apparently the spoiler function would not work, so ive added more spacing, apologies)

In the future if you could please, either drag and drop the file icon onto a forum post box or else upload them somewhere else and provide a link so we can get to and read them. The copy/paste thing is really difficult to read as it drops formatting.

I may be missing something here, but many of your NRaas mods are years out of date and I'm not sure some of them were even meant to be run on current patch levels. Could you try bringing everything up to date to see if that helps at all?

Careers 86 (current is 87)
ErrorTrap 98 (current is 100; be sure to select the Steam variant of 100 as I believe you have a Steam/1.67 install)
MasterController and MC Cheats 133 (both current are 134)
Overwatch 116 (current is 122, yikes)
Register 79 (current is 81 and this could be a major culprit here)

NRaas mods aren't the only thing out of date here. There's outdated tuning mods causing that and likely other issues. I'd dump the whole mod folder or review each one for updates.
