@Uncle Jessie,
Just tested out both your latest versions of 'cant block Tank on ladder' scripts from post 9 & 11, and it's not working as intended. I tried both your plugins for the normal ladder and the cradle (safety) ladder using myself to block the tops of each type of ladder (see linked screenshots for those ladder types). Mr Tanky just remains at bottom of ladder and wont attempt to climb, unless of course I move off of the ladder.
I've only tested this out on a two maps on my Windows L4D1 server. If you decide to update your scripts again, I'll be more than happy to test them out for you.
