I’ve been getting this error alot lately, here’s the Exception:

System.InvalidOperationException: Collection was modified; enumeration operation may not execute.

It’s been happening with pretty much all my torrent indexers, the builtin ones, the generic rss ones and the torznab ones.I’m on Ver. 2.0.0.3288 develop.

You get the same error with all of them? I know TL uses cookies and its entirely possible something is wrong there, but the other indexers don’t to my knowledge.
