In 1.4, the companion system recieved an overhaul, with all companions now being stationary, being recruitable from only one specific location. **Denotes companions that do not like raiding (at least so far). The lists below conflict with each other in your party, you'll have to pick the companions grouped together for the first column or second column in the same row to have a stable party (i.g Alen Clargyl, Fenna, Maron or choose to use Roderick and Ser Bennis Hollow Hill). *Note that you CANNOT disable companions disliking each other by going to the 'Mod options' menu in the camp screen and ticking 'disable companion complaints'. Not all Companions get on with each other and having ones that dislike others will cause friction in the party.
I've filled in the ones I found if you don't use 'gather companions option. **As of 6.0 Companions start in specific towns and stay there. *Tested at Version 1.4 without Mercenary Companions Updating for ACOK 6.2, Should be accurate (at least more so than before). This list will be updated as these preferences are known.
Please, add more information and custom charts, these should only be temporary. A nice chart done by Sergio_Morozov (version 2.1)
