corrupted save file (?)

[Ponali]

i have a save file where i made a lot of stuff, like 8-bit registers, 8-bit adders, etc, after some hard work
however, after a couple of days, i got a log window saying that "2-BIT RAM" doesn't exist (even though it does in the save files)
because the game thinks so, then it says that it's not possible to load the "4-BIT RAM", "8-BIT RAM", and "16-BIT RAM" chips. however, the chips "4-BIT RAM" and "8-BIT RAM" still exist in the chip selection footer, even "2-BIT RAM", but not "16-BIT RAM".

i haven't tested the chips, however you can get the save file from this:
