When I open Blockland, my screen goes black for three minutes (I just wait).
But, if I delete all of my add-ons, it doesn't go black at all, Blockland opens immediately.
So, I'm guessing that it just takes my Blockland a while to load because of my high amount of add-ons.
Do ONE of the following:
1. Delete all of your add-ons and then open Blockland.
If the screen still goes black, take someone else's advice.
If Blockland opens immediately, then you can put all of your add-ons back, but you'll still have to wait a few minutes for Blockland to finally appear every time you open Blockland.
2. Open Blockland and then wait a few minutes (I'd go with five).
If the screen is still black after five minutes, take someone else's advice.
If Blockland opens after five minutes or less, then you'll just have to wait for Blockland to open because of your amount of add-ons.
