 ### TODO
 - review visibility of methods/classes
 - more sensible error dialogs
-- check licenses of included libraries; License Dialog
 
 ### Issues / Pitfalls
 - Created wallets on a private testnet are unusable because the restore height is set to that
 of the "real" testnet.  After creating a new wallet, make a **new** one by recovering from the seed.
 The official monero client shows the same behaviour.
+- In rare occasions the monero core code returns a wallet address with corrupted characters -
+in these cases Monerujo crashes on purpose to make sure nothing bad happens
 
 ### HOW TO BUILD
 No need to build. Binaries are included:
 
 - openssl-1.0.2l
