when i copy/paste a medium or large structure with sams and turrets i start lagging really bad and have to restart.  Does anyone else have this issue?

nevermind

i had turned on copy trees bc i was trying to capture a giant tree in the swamp...
but then 6 squares range from entities... caught trees all around
then when i pasted first time it put all those trees
then i went and put more work into the base and copied it again
so i added all the additional trees accidentally ...after 3 or 4 times i had lots of trees by accident
THEN on pasting i was lagging so hard instead of undo i used remove structure which didnt remove the trees of course
then on next paste, like 4 times i pasted too low.. and remove structure each time and i was leaving hundreds of trees underground!!  Long story short i had hundreds of trees above and below ground and that was the issue.
