* Adds error on qdeling callback, fixes errors this causes (#77850) ## About The Pull Request You shouldn't ever qdel a callback. If you don't want to own it free your ref (remove it from a list/set it to null). When all refs are cleared it'll get cleaned up by byond itself * Adds error on qdeling callback, fixes errors this causes * Update cell_component.dm * Update acid.dm --------- Co-authored-by: LemonInTheDark <58055496+LemonInTheDark@users.noreply.github.com> Co-authored-by: Giz <13398309+vinylspiders@users.noreply.github.com>
