Seems to be an issue with the way numbers larger than 32768 are imported into AE from a CSV file for data-driven animations.
Steps to reproduce:
1 - Import CSV with numbers smaller and larger than 32768 and add to comp.
2 - Drag out Number data from CSV to composition.
3 - Notice that any numbers larger that 32768 are imported as being "32768" (E.g: Number data point should be 40,000, imports into AE as 32768.
