Description of issue:

Brigadier is sorting nodes every time a child is added as seen here. This was tested on 1.13.2 but this likely is still an issue in the newest version. I believe that this issue is somewhat resolved due to #3116 but it could still be useful. This issue seems to be resolved by deleting the sorting line and making the children map a TreeMap. The issue occurs on login or world switch and may be related to previous issues discussed. This fix has been on a production server for a month with no noticeable issues. Not sure how reproducible this will be on the latest builds due to #3116 but let me know if I should try to reproduce this on a newer version.
