Bug Report: 'spam_line_count'

Whenever I open a world in MushClient 3.32 a window pops up that states:

Line xx: Value '0' too small in numeric attribute named 'spam_line_count'. Range is 5 to 500. (option 'spam_line_count' not set)

The line number xx varies from world to world, of course. I have looked at each xml file that generates this warning but I cannot find any such attribute named therein. It does not seem to affect anything, but....?

Every omitted attribute is assumed to have a value zero, which it then complains is out of range. It is because it was newly-added. I suggest just save the world. It will create the attribute "spam_line_count" and you won't see the message again.
