"Done" button in the editor does not respond with specific code

[KobbalTTY]

Paste the following code in a disk:

name "HNN"

every 20 ticks do

    -- enter prediction matrices
    input prediction_matrix from enter
    output retain 1 prediction_matrix to each sim
    forget

    -- generalized predictions
    input from sim
    output *_prediction to exit
    forget

    input from warden_sim
    output prediction to warden_loot
    forget 

    input from loot bottom side
    output to exit
    forget

end

every 2 ticks do
    input 100000000 fe:: from energy_enter
    output fe:: to each sim
    output fe:: to each loot
end

Do any change to the forget line right under the warden_sim paragraph.

The "Done" button does not respond to clicks.

I narrowed down the problem more. If any of the lines 20, 21, 22, 23, 24, 25 consist of 35 or less characters, the Done button stops working. @TeamDman

very strange. no errors in the logs on the client? does the paste button work on the manager gui without entering the text editor? does shift-enter work instead of clicking done?
