The top portion of the errors on your terminal is hidden. Though that may or may not be relevant since you appear to have no data for that baby, which could result from a load error but more often means that the data was lost due to an error in a prior session. If it is a load error, then it may be possible to recover the baby, otherwise it is completely lost. Though there is a complicated process for attempting to re-create the baby data, it is probably better to simply abort and get pregnant again.
Either way, I don't think updating the game will fix your problem as the loading of save files has not significantly changed. If anything it is likely to make this matter a tad bit worse, since without the Debug mod the game will default to crashing instead of the GUI being unresponsive(though they are effectively the same outcome). On the plus side, the save file will be compatible with v1.0d if it was made with v1.0a. Though, I have concerns about that since many of the baby data problems originate prior to v0.5.25
If the mod you speak of is the Improved Random Portrait mod or a portrait pack, then it will not be the source of the problem. Though most other portrait mods should not have this result, without being sure of which mod I cannot rule it out completely.
