Knife Preference Bugs

[lb]

Earlier today I set my preferences to Karambit for both sides at around 12PM / 1PM (NZT). These preferences were set to both Karambit (CT: Karambit T: Karambit), However throughout the day on some maps the preferences were not remembered and my knives were switched to Butterfly (CT: Butterfly T: Butterfly). Preferences would be remembered a certain time, however 1 / 2 hours later the preference would not be remembered and my knives would be changed to Butterfly for both sides (only for 1 map and then the knives preference would be remembered the next map, although Byte says maps have nothing to do with preferences). Anybody else having similar problems, please leave them down below if you do.

Keeping Track.

NOTE: Have not used knife plugin since the bug above occured ^

Different users preferences are being used for my knife according to Byte. Could be the issue?
