Does anyone know why there would be slack in the purchase line of a counterweight lineset? There is only one that I've ever noticed this problem with- the main curtain. I think it happened amidst a near disaster where main and valence fouled and we had several near runaways where all 4 of us had to grab the rope. Somewhere in the middle of this it suddenly went slack- the floor block moved up, and I thought it went back down, but I guess not all the way... Is this anything to worry about? Based on my experiece/ basic knowledge of the flysystem setup it doesn't seem like there could be a real problem-- but I thought I'd ask to be sure. How do I fix this? Feel free to PM me on this one if you don't want to post it-- Though I'm thinking this falls under normal use and maintnance and is okay.
