HELP! Mixing 3 or more textures with Eevee

HELP!

I’m trying to mix three textures together to make a landscape in Eevee but it doesn’t work. In cycles there is no problem, but in Eevee it turns pink.

I’m mixing textures with Mix RGB nodes, defining (fac) with different methods, but this should not make any difference.
What am I doing wrong?

Thank you in advance for any help.

Can you try checking the output of the nodes from right-to-left in your node graph (ctrl+shift+click if you’ve got node wrangler enabled) to find at what point the output stops being pink. Then let us know at what point in the graph it stops working.
