Numbered Steps to Reproduce Problem:
This problem started to start when i downloaded BYOND verson [457.1049]

Does the problem occur:
Every time? Or how often?
Yes. everytime i use my map editor in my dreammaker
In other games?
well. it looks like when im around the houses in Naruto GOA, i start to lag. this might be a cause of invisible multiple houses? because those houses are mroe than 32x32

When does the problem NOT occur?
Im not sure. i didn't really tried it yet but i think version 456 or under

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit http://www.byond.com/download/build to download old versions for testing.)
