[Bug] Skill invocation and instruction retention degradation

Bug Description
in the last week or two it has gotten very unreliable to call skills. I don't have a new increase of number of skills, maybe one new skill in that amount of time, but it has gotten far less capable of using skills. And very often the way that I use skills is by using a slash command. So the first thing I do is slash and the skill name, so it so will it force will a forcibly call it. But certainly it's losing instructions far more frequently than it did multiple weeks ago. Not just around skills, but even things that I'm putting in the instructions or memory files and things of that nature.
