Warping of the Platform Casing

The plastic casing surrounding the build platform has warped on all four sides after 30 hours of use.  It has pulled away by up to 1/8" and now when it goes into the resin, the resin gets inside the build platform.  essentially, it cannot be used anymore.  Prior to this happening, the previous print was tried without supports.  When the program was run, nothing was built.  Could this have caused the failure?
