Describe the bug

When installing an app, which contains tweaks in the framework folder, the tweaks seem to not get resigned.

In the previous version this seemed to work.
This happens on the latest commit of the nightly/multitask branch.

Not an app issue, as regular installation with sideloadly works as expected.

Tried force sign as well. Jit-Less Mode Diagnose shows all green.

Instructions to reproduce

inject tweak with sideloadly, export as ipa
disable tweakloader injection (same issue if enabled, but tried all settings)
run app
get signature invalid error for injected dylib

What version of LiveContainer are you using?

3.6.60-Release (multitask/07211a8)

Then I guess it's an app issue. Please send me the ipa, or you may try another ipa

It should be fixed by the latest build. Do note that this issue is caused by the tweak being so badly constructed that it confuses the signer.
