Journeymap Tools crashing while making a map

[Talyda]

It's getting to "current tile 347/957" when I am trying to export overworld daytime map, then giving me this error below

Just in case this is related, I have had journeymap crash me out twice on this server when I had been exploring a lot (not for the past three weeks) so I am not sure if that potentially corrupted the map, and that is what is causing the above error
this is one of the logs from three weeks ago, when it did crash me, just in case there is some kind of correlation between them

Likely due to a corrupt map tile
