WP Super Cache serves category page has homepage

Sometimes for certain users/browsers WP Super Cache serves the wrong cached page for the home page. Instead of serving the home page it serves a cached version of the first category page. It’s hard to reproduce the problem but we’re seeing it more or less daily.

I can fix this by clearing the entire cache, but this can hurt my SEO quite a bit if the googlebot lands on my homepage when this is occurring.

my .htaccess

# BEGIN WPSuperCache
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
AddDefaultCharset UTF-8
#RewriteCond %{REQUEST_METHOD} !=POST
#RewriteCond %{QUERY_STRING} !.*=.*
#RewriteCond %{HTTP:Cookie} !^.*(comment_author_|wordpress|wp-postpass_).*$
#RewriteCond %{HTTP:Accept-Encoding} gzip
#RewriteCond /mnt/stor1-wc1-dfw1/379363/www.mmohut.com/web/content/wp-content/cache/supercache/%{HTTP_HOST}/$1/index.html.gz -f
#RewriteRule ^(.*) /wp-content/cache/supercache/%{HTTP_HOST}/$1/index.html.gz [L]

RewriteCond %{REQUEST_METHOD} !=POST
RewriteCond %{QUERY_STRING} !.*=.*
RewriteCond %{HTTP:Cookie} !^.*(comment_author_|wordpress|wp-postpass_).*$
RewriteCond /mnt/stor1-wc1-dfw1/379363/www.mmohut.com/web/content/wp-content/cache/supercache/%{HTTP_HOST}/$1/index.html -f
RewriteRule ^(.*) /wp-content/cache/supercache/%{HTTP_HOST}/$1/index.html [L]
</IfModule>

I commented the top section out because my host recommended it to me. [mosso cloud hosting]. I have Super compression set to disabled in the backend, but it still gets super compressed. Even if I don’t comment the top part out, i still get the same error of my category page being cached as the homepage.
