Large numbers in repeat blocks show up as zero

[BryceLTaylor]

If a repeat block has a large number in it, such as 99999999999999, when brought into 3.0 it appears as a 0.

Steps to reproduce

load project # 115120 in 2.0
Select the "stick" sprite
Note: it contains a stack that looks like this:

Note: the repeat loop contains the number 99999999999999
Load that project in 3.0 and select the stick sprite
Note: that same stack looks like this:

Note: the repeat loop contains the number 0

It is possibly deciding that that number is too big and deciding it's a string, therefore an invalid input and replacing it with a 0.

If you set the number in the repeat block to a really big number and fix the problems found in issue #1 it makes the game playable. It's hard to see the issues that this causes without making both changes to the project.
