In this mod...http://custom.simplemachines.org/mods/index.php?mod=475 Once you upload an award you can't edit it in any way, or delete it. Every time you try to edit or delete it says the award doesn't exist....and this is on SMF 2.0 Beta 4
You should probably look through the support topic for that mod and see if the issue is seen by others. If not, post your question about that mod there and the author or someone doing support for the mod can help.
