This is part of the quests "X-8: High School Horror" and the "Sonic Emitter Upgrade" retrieval quest. In order to successfully finish both of them, I need to re-enter the institutional test at several times. However, after doing the instituational test once, I accidentally started the residential test. Now, it seems like I can't switch back to the institutional test anymore. The residential test also doesn't seem to contain the item, I'm looking for. As a result the quest seems to be locked since I can't finish either of the two tests.
Is there a way to reset the terminal which controls the tests? Maybe a console command? Has anyone ever had this problem?
