Firmware 4.2.x is out as snapshot firmware

I confirm that I’m facing the same problem that @mainufer described, with VPN client turning yellow after some time and remaining yellow forever. Differences are that I’m not using Torguard but Mullvad, I’m not on GL-AXT1800 Slate AX but on GL-AX1800 Flint. I’m also using 4.2.0 beta2 firmware version. I alson confirm I wasn’t experiencing this in 4.1.0 stable (although I didn’t use the VPN client much on this version while the VPN cascading didn’t exist).
