IPsec mobile clients stop connecting after adding an additional site-to-site entry

[AceStrider1]

I have a “Main Site (pfSense 2.5.1)” and a “Remote Site 1 (pfsense 2.5.1)” connected via a site-to-site IPsec tunnel.
I also have on the “Main Site” IPsec mobile client support enabled.
Everything is working as expected.

When I add an additional site-to-site phase 1 entry to a “Remote Site 2” the mobile clients (Android phones and tablets) are no longer able to connect. As I already had a preexisting site-to-site tunnel, I would not think adding additional ones would be an issue. I am having the issues as soon as I add the phase 1 entry for an additional tunnel. Are there any know issues?
