I apologize for the delay in my response
@AnotherJohn it sounds like you misunderstand how the plugin works with the different modes.
You are using a macro AND /rog mode assist
You can do that, though you're likely going to get some unexpected results from it due to this.
The "manual" mode is intended to let you do all steering of the character, or allow a macro to conduct all steering. It also allows you or a macro to determine if you want to engage with an NPC, as it doesn't automatically select your target, or engage. However, it will use any abilities available to it during combat, or downtime as needed.
The "assist" mode (the one you say you are using) /rog mode assist or /rog mode 1, does not need anything else to operate. It will create a camp at the location you are standing when you use the command to switch to assist mode. It will then assist the groups MA (The MA must be assigned via the right click context menu from the leader to assign the Main Assist role to the character you want to assist). It will do all combat and downtime things as needed and it will return to a camp location.
The "chase" mode is very much like the Kissassist /chase on mode where there is no camp set, and instead the camp is the MA. Whereever the MA is standing is your camp, and if you are not within a specified distance from the MA and not in combat, the rogue will attempt to follow the MA. If the MA enters combat, and the MA's target goes below the "AutoAssistAt" value, then the rogue will assist the MA in combat, once combat is concluded they will resume following the MA. Buffs are only attempted if the rogue is not in motion.
If you want to use a macro to follow the MA then you need to /rog mode 0, or /rog mode manual
If you want the plugin to handle the camp then you do /rog mode 1 or /rog mode assist
if you want the plugin to handle chasing then /rog mode 2 or /rog mode chase
If you have any issues, please let me know.
