First off...
God dammit, stupid text thing. I tried to make it smaller. -_-
Sorry for double post.
Use an end tag, lol. [ code ] tags work pretty well too (click the
button on the post page), or better yet you could attach the console.log to your post. In the post page, click the Additional Options... bit below the text box, then use the Attach box down there.
Regarding the actual problem though, try not to be impatient.
If you try to send commands (clicking/typing) to Blockland while its busy doing something (starting up,
saving, etc) Windows may come up and say "Hey, this program isn't responding to your input! It probably crashed, want to end it?"
The possible problem here is that Windows
thinks BL crashed when it's just doing a big task. If a window comes up saying "Blockland has stopped responding. >Wait for program to respond >Close program now" then choose to wait a bit. It should be able to finish with time. However, if it does nothing in a while, you may want to end it.
A different possible problem could be that your computer simply can't handle large brick saves (causing an insta-crash) in which case I can't really help you there. How much RAM do you have anyway?
