Hey thanks for this! Looks like when I updated the files for the CRG release I accidentally uploaded an older file. I've gone ahead and uploaded new versions (v1.6) of all the core game files that should be all fixed up. To clarify, Critical Successes award +1 Success and -1 Stress (+2 Successes in combat).
There's a small blurb about item weights in the Items section of the Employee Handbook (pg 04) but item weights and ranges aren't tied to any mechanics or hard rules. sort of loosy goosy I know but it keeps it light and doesn't bog down play. Feel free to add anything you'd like and please let me know if you do. Always love when people tinker around in there.
Thanks again!
