Regenerate incorrect pcode generated by old version of ghidra

[12Me21]

Is there a way to regenerate all pcode in a project, without having to clear the instructions?

This project was started in a version of ghidra which didn't handle 68000 byte moves with autoincrement correctly. (among other things)
e.g. here it should decrement A0 by 1, but instead decremented it by 2:

    00006260 11 00               move.b        D0b,-(A0)
                                                      $U24d00:1 = COPY D0b
                                                      A0 = INT_SUB A0, 2:4 ← should be 1:4
                                                      $U8b80:1 = COPY $U24d00:1
                                                      STORE ram(A0), $U8b80:1
                                                      NF = INT_SLESS $U24d00:1, 0:1
                                                      ZF = INT_EQUAL $U24d00:1, 0:1
                                                      VF = COPY 0:1
                                                      CF = COPY 0:1

That bug has since been fixed, but the pcode in this project is still incorrect (and this affects the decompiler as well)

If i clear the instruction and disassemble it again, the pcode is correct:

    00006260 11 00               move.b        D0b,-(A0)
                                                      $U24d00:1 = COPY D0b
                                                      A0 = INT_SUB A0, 1:4
                                                      $U8c80:1 = COPY $U24d00:1
                                                      STORE ram(A0), $U8c80:1
                                                      NF = INT_SLESS $U24d00:1, 0:1
                                                      ZF = INT_EQUAL $U24d00:1, 0:1
                                                      VF = COPY 0:1
                                                      CF = COPY 0:1

But i can't just do that to the entire project, because that also deletes references etc.
