Print bed deformation
I just made a quick print overnight and got up in the morning and took the print off the bed. These marks were left on the bed and if you move your finger over them you can feel the bumps. Here is a pic. I am new to the Prusa guys so forgive me if this is a routine question.

Routine question: no apology needed: But many forum threads asked and answered.
Perfectly normal. The bumps will resolve in time. And next time, don't forcefully remove parts from a HOT bed.
To speed up PEI glue layer healing, flip the sheet and use the other side for a while.

Ok thank you. Hopefully it will cure itself. This print was sitting for 3+ hours after it finished so it wasn't that for sure. I am building the block templates to align my CR10S pro Z axis. So there were two identical pieces almost side by side. You can JUSt see the mark on the left which was the second piece. When I chatted with the live chat online they said that the nozzle might have been too close. I can't see that being the problem at all or else the print on the left would have left the same mark. They are only separated by 2cm at most.

On a clean bed, PLA sticks really well, as does PETG. PET actually sticks so well people will spray Windex on the surface to reduce the stick. I'll Windex and wipe my hands all over the bed when printing PETG ... it took an hour to remove my first PETG part - any faster would have shredded the PEI layer.
Flexing the sheet usually breaks a part free; and if that isn't doing it (like with PETG), 15 minutes in a freezer also does wonders.

Oh there was no problem whatever taking the prints off. They almost feel off by themself
