You are getting some weird bugs, I play this for a long time and neither saw this kind of bugs.
But to the 1st topic, do as cravenge said, try to remove francis with Stripper
You can check some info
here , is an old dump file but you will see that there is an entity called "francis".
Here is some of then:
"targetname" "francis"
"targetname" "francis_start"
Try to remove each one (with stripper) and check if it "fixes" it.
And about the 2nd, seems more like that the pistol is being replaced by another plugin.
Try to use a vanilla server (without plugins) and check if this weird behavior occurs.
