1. OSBot Version (do NOT put "current version", be specific)

2.4.147

2. A description of the issue. Include relevant logs.

Calling getStore().buy(itemName, 50) throws an NPE at api.Store.getSlot. The item I am buying is available in store.

3. Are you receiving any errors in the client canvas or the logger? 

Yes, see above.

4. How can you replicate the issue?

Call getStore().buy(itemName, 50). Not sure if it happens with other buy amounts as this has been reported by a customer I wrote a private script for.

5. Has this issue persisted through multiple versions? If so, how far back?

Was working fine till the recent buy 50 update.

When was the buy 50 update?

The report is kind of misleading, as it has nothing to do with "buy 50", but buying in general. Still looking into it, locking for now.

Turns out I was never given the new hooks and went down a pretty terrible path of bug testing. Your issue has been resolved on the next release.
