Ah, so there's actually a different issue at work here. Do you have the Play as Jessie in Reactor 1 mod active? I didn't add an event where you have to pick up Biggs on the way up but I think the Jessie mod does so this might be what's interfering with the event handling (unsure of full impact). I'd advise trying this part out without that mod active (if it is installed) and hopefully it'll work. If not, I'll either need the save file or a start over will be needed without that mod active.
Hi Sega Chief, you are right, I think I enabled Misc. catalog which has Jessie Mod enabled (

In the elevator where Jessie Mod supposed to trigger, I did not really recruit her but the script clash still happens.
After I disable it, Biggs no longer appear, but the gate is still closed.
I actually need to restart a new fresh new game again for it to fix.
Thank you for your prompt response, I really appreciate it, keep up the amazing work my man.
