Non Spawning or Dropping Sentry

Ok so I made sure that my sentry should spawn and drop an item but it will not work.

What doesn’t work? The spawning or the dropping?

Is there a chance?
Set it to 100 if there is.

Just the dropping doesn’t work

Is this in platforming?
Please give pictures.

Do you mean that the sentry will fall after it spawns, or that it won’t drop items when knocked out?
