Techne Mob Error?

Hi, today I wanted to create a model for a creature in the old version of Techne. Suddenly, by creating the creature in MCreator, an error occurs, and I suspect that this is relative to the size of our creature. Maybe too big? Finally, I let you look at the mistake:

C: \ Pylo \ MCreator179 \ forge \ build \ sources \ main \ java \ mod \ mcreator \ mcreator_strongDerpy.java: 184: error: illegal start of type "strongderpy", mobid, instance, 64, 1, true, (240 16 ) + (0 8) + 49, (160 16) + (0 8) + 185);

Yes, this error has actually happened to a modder who wanted to create his model, when, suddenly, a singular error to it occurs, which is an error that I prefer not to calculate. I give you time to calculate and answer for my continuations. Otherwise, good evening!
