More info about this: the logs above shows regarding because there are now checkwall code in RL#template's OnDisable.

The bug I'm referring is this:

those barricade should be hittable since Guardian Stones are down again. Then i tried reading changes regarding agit_main_se.txt and saw #1596, after reverting this. and trying to reproduce the bug again using the steps. I can now destroy those barricades.
