Exactly what it sounds like. I was testing a skin with a very long !Execute series: 156 bangs, in 5853 characters. Rainmeter ignored the rest of the line after approximately 102 bangs, or 4107 characters. This was not an issue in r181.

(Original skin attached if helpful. We realized the problem when we discovered that removing the spaces between commands ("] [") reduced the number of commands being dropped.)

Fixed in r206.
