Hey Hanna Brassheart and Aislinn Mollisong1, thank you very much for your help! I managed to find some solvent by myself (it was behind the big tower in the Town Square) which allowed me to make dynamite so i could blow up the shipment and for doing that Alexander gave me some steam which allowed me to fix Selina's wheelchair. Thank you Hannah Brassheart for helping me find the satchel, i was so obsessed with getting rid of the fire in front of the robot because i thought that was where i would find the satchel that i wasn't looking in the area for it. I found it and now am on the right path. Thank you again very much!
