There is no need to shout. Mario's theory was entirely plausible: if
some command in the script returns non-zero and prints nothing to
stderr, that will entirely explains the symptoms you saw, both before
and after removing the -e.

This relies on knowing that -e to sh means "exit the shell as soon as
any command exits non-zero".

The minimum example of this theory is:
[[[
#!/bin/sh -e
false
true
]]]
