oh god the reason is even stupider then I expected

Because large numbers use the e character in their string representation (e.g., 6.022e23 for 6.022 × 1023), using parseInt to truncate numbers will produce unexpected results when used on very large or very small numbers. parseInt should not be used as a substitute for Math.trunc().
