Contract ticker (LP Token) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

FEGexPRO (#380-1092) should inherit from swap (#227-232)
Inherit from the missing interface or contract.
