Could my platform be bent?

[ixlr8]

I know this is an old post but I am having a similar issue that ixlr8 describes. No matter how carefully I level under the level screws, the center is always high. I thought my build plate was warped so I installed a glass plate and it is still high in the center with new glass. So it seems that the extruder guide rods must be sagging in the center. I have tried slightly rotating the rods in case they were bent (theory being if the rods are bent down then rotating would show high in the center after rotating) but no change after rotating rods.
Has anyone come up with a fix for this?

I lived with it.

Until my platform went bad, then replaced it. Now it's much more level than the last one!

One advantage of using a glass plate is to make up for any warping of your build plate.

Helps but not essential. There are many surfaces that also work just as well.
