For levels beyond 370, I've uploaded the pictures onto this wikia up to 390. I may edit them eventually once I got the time again to do so, but in the meantime, these pages are already available for them, so there won't be needs for uploading pictures of them. I'm currently on Level 392 and will soon working on the pages and pictures for them.
I'm glad you are returning to help out on Diamon Digger Saga Wiki again!
Last week I noticed there are way too many levels that looks entirely different than the ones shown in the map, and they need to be updated.
There is a tracking template called Template:Updated temporarily for recording down which levels are recently checked. If a level has been recently checked by you and are completely the same as the page displays, you can record down with |Level xxx = Feb25 for levels that are checked between Feb 25 ~ Mar 3. If a level is different, just change the page completely into the new version. If the change is too complicated or there are not a lot of time to do so, simply mark it as "Bad" and I'll immediately take a look on it.
I finished checking Levels 1 ~ 25 and will move on to the next few episodes.
