Hi, owner here!
FlewwRBLX is correct. We've decided to focus on SD2 content from here onwards, as we feel it's much easier to manage, especially with V42 on the horizon.
In hindsight, we shouldn't have marked all the disaster pages for deletion, just the game page and anything that isn't in SD1.5, since they are still technically part of SD2's history. If you see a disaster that was in SD1.5 and it's marked for deletion, go ahead and unmark it! We will still be removing content that was not in SD1.5 and any other content that is irrelevant to SD2.
If you are concerned about preserving SD1 content, don't worry, so am I! I heavily suggest joining our Discord server and talking to me there. We can sort things out! https://discord.gg/RPcK73Y
