I tried to get onto Skyblock but it crashed. Then a notif. came up saying "We're sorry, but Minecraft encountered an error while rendering the world. If you were trying to play on a multiplayer server, please contact the server administrators. JIRA issues: MC - 103981" What do I do?
It is an issue with Minecraft 1.10.1, please downgrade to any version between 1.8-1.10 to play on the server. Mojang has tweeted that they are going to fix this issue in Minecraft 1.10.2.
1.10 isn't at all that reliable, seen as it came out not long ago. What I suggest, is to follow Wilbo's advice, downgrade your MineCraft version to 1.8.9 or 1.9, as the server is more stable on those versions and it's a lot more reliable.
This usually works for me: Copy and paste all your important folders from the .minecraft folder into a separate folder (on your desktop, documents...) such as screenshots, saves, server list. Delete the .minecraft folder Download a clear Minecraft installer Install Minecraft If this doesn't work please reply EDIT: First do what other people are suggesting.
That is good advice, however this happens to everybody running minecraft 1.10.1 at the moment. The only way to fix it is to wait for Mojang to put out the 1.10.2 patch. In the meantime, please consider downgrading
I keep two downloads of minecraft on my computer and I switch between them but im not sure that works the same way as your advice.
It seems that these people have answered your question. Could you reply within two days or so if your question has been answered?
