0 tic/time handling
Modern Dday with it's higher precision math (I assume this is the cause) is unable to handle 0 tic/time lengths in ded's reliably (i.e XG, mobj defs etc) unlike 1.8.6; it seg faults, infinite loops etc.
May I raise the possibility of DDay automatically correcting such (i.e automatically converting 0 time values to the equivalent of the minimum amount of time the definition type supports? To avoid fatal errors and crashes in Dday.
I suggest an automatic correction because older mods may have used 0 tic/time values.
