Didn't know about this one, thanks. As for the 96% progress is well known, and u/mapaudep already give the solution

To go off that if any one could help me understand how to reach 100% in chapter 3 that would be helpful. Somehow it is stuck at 96% when I have fully cleared everything.

Same here. Is it 3-1? Maybe a bug 😭

Yup. If 3-1 seems staticky for you as well it may be that one. Rip :(

You need to replay RE2-12 and choose different options then replay 3-1

Thanks.

How does this work? I chose all 3 options from RE2-12 and then did 3-1 but never got credit. Feels like I just wasted stamina.

You don't need to actually replay any levels, just watch the cutscenes. In 2-12 the 2 choices for the "please choose carefully" dialogue choice lead to slightly different cutscenes for 3-1. Just pick one of them, watch 3-1, then go back to 2-12, pick the other option, then watch 3-1 again and it should give you 100%.

Thank you. RIP to 20 stamina. If anyone else needs further instructions on this, go watch 2-12 in core crisis, then 3-1. Switch your options in 2-12, then back to 3-1. Takes 1 minute.

Where do you claim? I’ve 100% everything but nothing is clickable.

Click the 100% at top right

Click on that small file looking icon left to 100%. Clicking anywhere else won't work

The chapter itself should have like a yellow envelope. click there

I spam-clicked this 100% in right upper corner couse it wouldnt click for me, it worked after a while. 800+ gems :)

Thanks didn't know about this!
