To fix a buffer overrun you need to know what a Blockland buffer overrun is.
A blockland overrun happens when a bad add-on corrupts the program ".../Blockland.exe"
To fix this you need to...
#1 - Go into the blockland folder and double click the file called console.log (open in .txt) this is a error reporter
#2 - Click on edit and then find and in the box and type "Syntax error" in the find box
#3 - When you find one look at the left and that will tell you the add-on name.
#3 - example: Loading Add-On: Weapon_Sgrenade
Add-Ons/Weapon_Sgrenade/server.cs Line: 394 - Syntax error.
>>> Some error context, with ## on sides of error halt:
function SgrenadeImage::onDone(%this,%obj,%slot)
( You need to delete the file "Weapon_Sgrenade" )
#4 - Delete any file that has "Syntax error" by the name in the
add-ons folder.
Hope this helped you solve your problems on this topic.
